Abstract-Line shifts, originating in a discharge tube crossed by a high current, are presented for Kr II, Kr III, and Xe III. We find regularities between shifts that may be attributed to the microscopic Stark effect.
INTRODUCTION In a previous study, Di Rocco et al’ reported the shifts of Xe lines produced in high-current, pinched discharges. These shifts were observed when comparing values obtained by Gallardo and Almandos’ and by Humphreys.3 Using a collisional model, we showed that these shifts depend on the energy levels involved in the transitions and may be ascribed to the microscopic Stark effect. We have obtained and studied spectra belonging to Xe III, Kr II, and Kr III. The results have been compared with those of Humphreys. @ We have found similarities between line shifts for 5s-5p, 5p5d, 4d-5p, and 5p6s transitions in Kr and 6&p, 6p6d, 5d-6p, and 6~7s transitions in Xe. The observed line shifts may be assigned to the microscopic Stark effect. EXPERIMENTAL
FACILITIES
For Xe III, the experimental details are the same as those used previously for Xe II.’ For singly and doubly-ionized Kr, the same light source was used as before.’ All spectra were obtained with spectroscopically pure gases. RESULTS
AND
DISCUSSIONS
In Tables 1-3, we present representative results for Xe III, Kr II and Kr III, respectively.? In the first column, we give the line classification. In the second and third columns, we show our measurements and those of Humphreys (subscript Hum), respectively. In the last column, we give differences between these measurements. For Xe III, the line classification is based on a complete study by Persson et a1.8 Classifications of Kr II lines are based on Ref. 5. For Kr III, the classifications are based on Ref. 6. The last columns in Tables l-3 show similar trends in the shifts for lines corresponding to similar and equivalent transitions. For the 6~7s and 6p6d transitions in Xe III, line shifts have generally the same sign as in the 5~6s and 5p5d transitions of Kr II and Kr III. Similar trends were observed previously’ for the 6p6d and 6~7s transitions in Xe II. We note similar differences between the 6s-6p in Xe III and 5s-5p transitions for Kr II and Kr III. Finally, line shifts for the 5d-6p transitions in Xe III show the same erratic differences as the observed for the 4d-5p transitions in Kr II and Kr III. The average values of the line shifts have similar magnitudes for isonuclear species (i.e., Kr II and Kr III, as Xe II and Xe III). tMore
