Synopsis The Cu IV spectrum has been observedby means of a 6.650m vacuumspectrograph. All levels of all multiplets of the calculations 3d s, 3d74s and 3d74p have been found. Results of least-squares calculations are presented in the form of parameter values which are in satisfactory agreement with current figures for other spectra of the 3d-group. The detection of a number of levels of the 3d75s configuration made it possible to determine the ionization potential at 55.2 V.
1. Ihoduction. The study of the spectra of doubly- and trebly-ionized atoms of several elements is in progress in this laboratory since the completion of a 6.650m vacuumspectrographi). During the preliminary work with the spectrograph a sliding spark2) containing copper electrodes was used because of the many Cu III liness) known in the vacuum region, which could serve as standards. Apart from that publication we disposed of an unpublished extension of the analysis of the Cu III spectrum made by Shenstone. Our spectrograms were extremely rich in lines and around 300 hitherto unknown Cu III lines could be classified as transitions between known levels. However, many other strong Cu lines, which could not be classified as Cu III transitions were observed in the wavelength region where the 3d74p -+ 3d74s transitions in Cu IV could be expected from extrapolation in the iso-electronic sequence Fe I, Co II, Ni III, Cu IV, namely the region 1500-1300 A. Since the transitions 3d74p -+ 3d* should lie in the region 600-400 A this region was explored subsequently. In spite of the poor reflectivity of the grating in first order) a number of very strong lines were dis(blazed for 1500 A covered in that region indeed. Another region with strong lines of similar nature was found, namely the region between 1100 and 900 A. Many of these lines belong to transitions between levels of the 3d75s-3d74p as will be shown in section 4; the rest probably should be regarded as 3d74d+3d74p transitions. 2. Experimental part. The experimental procedure was the same as that described by Poppe for the observation of the Ni IV spectruma). By using 388

peak currents in the sliding-spark lightsource of 1000, 500 amd 120 ampere, at a He pressure of 2 torr, lines belonging to the different spectra of copper (Cu II, Cu III, Cu IV) could unambiguously be discriminated (fig. lb-f) in the whole region (2450-350 A) studied. With a current of 1000 ampere the lines of Cu IV are enhanced and at lower currents the spectra of Cu III and Cu II are strongly favoured. A confirmation was obtained by increasing the He pressure: the spectrogram reproduced in fig. la has been made at a pressure of 20 torr with a current of 1000 ampere, with the result that only the IV lines are strong. The spectrograms have been made on Ilford Q2 and Kodak S.W.R. plates. They have been measured by means of the semiautomatic COSPINSCA5) and the automatic ‘ZELACOM-V’s) comparator. The method of wavelength evaluation has been described elsewhere496). 3. Analysis. In table I the theoretical even and odd configurations and terms to be expected low in Cu IV are displayed. By the kindness of Shadmi7) we could dispose of predicted level positions in the Cu IV spectrum, derived from the Cu II and Cu III systems, which had been treated as part of a general description of II and III spectra in the 3d-period 879).

The analysis started by finding the two triplet terms sF and aP of the ground configuration 3ds from the strong combinations with 3d7(4F)4p, a(GFD)a and s(DPS)a in the region 560-480 A. The relative positions of the levels within each configuration are in good agreement with the predictions, but on the average the 3d74p configuration is some 700 cm-l higher with respect to 3ds than predicted. In a similar way the 3d7(4F)4s sF term was located some 1800 cm-i lower than predicted. Again the predictions were very useful because the intervals and term separations within the configurations came out quite accurately. After the quintet system had been established, which explains the rest of the strong Cu IV lines in the region 1500-1300 A as transitons 3d7(4F)4p 5(GFD)a --f 3d7(4F)4s SF, a new calculation was set up specifically for Cu IV by Noorman and Ouwerkerkia). The closeness of the fit can be

The significance of the symbols is the same as given by Noorman and Schrijver 11). The first column gives the symbols, the second column gives values of the parameters predicted from their general least-squares fit in the IV spectra and the third column the values obtained in the least-squares calculation in Cu IV only. The parameters 01, /? and T are fixed at the values derived from the article, except 01in the 3d74p configuration. In table V all transitions in the Cu IV spectrum are listed according to

The intensity numbers are on a scale from 1O-400 and have been estimated from photographic densities. Of the total intensity attributable to Cu IV lines in the regions 1500-1300 A and 600-400 A, more than 90% belongs to lines which have been classified. Of 218 possible transitions between levels with the same parent term and the same multiplicity in the configurations 3d74s and 3d74p, 189 have been observed, that is 87%. All other possible transitions between these configurations can produce 1629 lines. We found 240 of them , that is IS%, and many of these lines are weak as can be checked in table V. From this it can be concluded that the d7-core which is characterized by a rather pure LS coupling (as is ds), is little affected by the addition of a 4s- or even a 4pelectron and it casts doubt on the adequacy of the Russel-Saunders notation used. The eigenvectors obtained from the calculations, however, learn that the assignments are unambiguous in most cases; only in the 3d74p configuration some of the states show considerable mixing of LS functionsrz). 4.

This immediately led to the detection of the levels 5F5 = 288 882.5 and 5F4 = 289 934.0 cm-r, which confirms the Ni III identifications made by Miss Garcia, as opposed to Shenstone’s which had been used in vain previously.

Synopsis The Cu IV spectrum has been observedby means of a 6.650m vacuumspectrograph. All levels of all multiplets of the calculations 3d s, 3d74s and 3d74p have been found. Results of least-squares calculations are presented in the form of parameter values which are in satisfactory agreement with current figures for other spectra of the 3d-group. The detection of a number of levels of the 3d75s configuration made it possible to determine the ionization potential at 55.2 V.
1. Ihoduction. The study of the spectra of doubly- and trebly-ionized atoms of several elements is in progress in this laboratory since the completion of a 6.650m vacuumspectrographi). During the preliminary work with the spectrograph a sliding spark2) containing copper electrodes was used because of the many Cu III liness) known in the vacuum region, which could serve as standards. Apart from that publication we disposed of an unpublished extension of the analysis of the Cu III spectrum made by Shenstone. Our spectrograms were extremely rich in lines and around 300 hitherto unknown Cu III lines could be classified as transitions between known levels. However, many other strong Cu lines, which could not be classified as Cu III transitions were observed in the wavelength region where the 3d74p -+ 3d74s transitions in Cu IV could be expected from extrapolation in the iso-electronic sequence Fe I, Co II, Ni III, Cu IV, namely the region 1500-1300 A. Since the transitions 3d74p -+ 3d* should lie in the region 600-400 A this region was explored subsequently. In spite of the poor reflectivity of the grating in first order) a number of very strong lines were dis(blazed for 1500 A covered in that region indeed. Another region with strong lines of similar nature was found, namely the region between 1100 and 900 A. Many of these lines belong to transitions between levels of the 3d75s-3d74p as will be shown in section 4; the rest probably should be regarded as 3d74d+3d74p transitions. 2. Experimental part. The experimental procedure was the same as that described by Poppe for the observation of the Ni IV spectruma). By using 388

peak currents in the sliding-spark lightsource of 1000, 500 amd 120 ampere, at a He pressure of 2 torr, lines belonging to the different spectra of copper (Cu II, Cu III, Cu IV) could unambiguously be discriminated (fig. lb-f) in the whole region (2450-350 A) studied. With a current of 1000 ampere the lines of Cu IV are enhanced and at lower currents the spectra of Cu III and Cu II are strongly favoured. A confirmation was obtained by increasing the He pressure: the spectrogram reproduced in fig. la has been made at a pressure of 20 torr with a current of 1000 ampere, with the result that only the IV lines are strong. The spectrograms have been made on Ilford Q2 and Kodak S.W.R. plates. They have been measured by means of the semiautomatic COSPINSCA5) and the automatic ‘ZELACOM-V’s) comparator. The method of wavelength evaluation has been described elsewhere496). 3. Analysis. In table I the theoretical even and odd configurations and terms to be expected low in Cu IV are displayed. By the kindness of Shadmi7) we could dispose of predicted level positions in the Cu IV spectrum, derived from the Cu II and Cu III systems, which had been treated as part of a general description of II and III spectra in the 3d-period 879).

The analysis started by finding the two triplet terms sF and aP of the ground configuration 3ds from the strong combinations with 3d7(4F)4p, a(GFD)a and s(DPS)a in the region 560-480 A. The relative positions of the levels within each configuration are in good agreement with the predictions, but on the average the 3d74p configuration is some 700 cm-l higher with respect to 3ds than predicted. In a similar way the 3d7(4F)4s sF term was located some 1800 cm-i lower than predicted. Again the predictions were very useful because the intervals and term separations within the configurations came out quite accurately. After the quintet system had been established, which explains the rest of the strong Cu IV lines in the region 1500-1300 A as transitons 3d7(4F)4p 5(GFD)a --f 3d7(4F)4s SF, a new calculation was set up specifically for Cu IV by Noorman and Ouwerkerkia). The closeness of the fit can be

The significance of the symbols is the same as given by Noorman and Schrijver 11). The first column gives the symbols, the second column gives values of the parameters predicted from their general least-squares fit in the IV spectra and the third column the values obtained in the least-squares calculation in Cu IV only. The parameters 01, /? and T are fixed at the values derived from the article, except 01in the 3d74p configuration. In table V all transitions in the Cu IV spectrum are listed according to

The intensity numbers are on a scale from 1O-400 and have been estimated from photographic densities. Of the total intensity attributable to Cu IV lines in the regions 1500-1300 A and 600-400 A, more than 90% belongs to lines which have been classified. Of 218 possible transitions between levels with the same parent term and the same multiplicity in the configurations 3d74s and 3d74p, 189 have been observed, that is 87%. All other possible transitions between these configurations can produce 1629 lines. We found 240 of them , that is IS%, and many of these lines are weak as can be checked in table V. From this it can be concluded that the d7-core which is characterized by a rather pure LS coupling (as is ds), is little affected by the addition of a 4s- or even a 4pelectron and it casts doubt on the adequacy of the Russel-Saunders notation used. The eigenvectors obtained from the calculations, however, learn that the assignments are unambiguous in most cases; only in the 3d74p configuration some of the states show considerable mixing of LS functionsrz). 4. Iorti.zatiolz potentzal. Unpublished Ni III levels, kindly communicated to us by Dr. 0. Garcia-Riquelmers), enabled us to extrapolate the position of the levels of the 3d75s configuration. This immediately led to the detection of the levels 5F5 = 288 882.5 and 5F4 = 289 934.0 cm-r, which confirms the Ni III identifications made by Miss Garcia, as opposed to Shenstone’s which had been used in vain previously. After that, the other levels of the configuration 3d75s were detected. With the Rydberg formula T = RP/(n*)2 adopting a An* equal to the value in Ti IVr4) (1.031), we calculated the limit to be at 445124 cm-r. This gives an ionization potential of 55.2 V.
