ABSTRACTS OF PAPERS TO APPEAR IN 3. PHYS. CHEM. SOLIDS

iv

chiometry is due to (1) differences in the number of sites over which the defects may be distributed and (2) changes in the total number of sites of the crystal as defects are formed. (Received 20 December 1966) 12.

ANISOTROP1E LOCALE DANS LE TELLURE MONOCRISTALLIN PAR RESONANCE MAGNETIQUE M. Bensoussan (Laboratoire B. P. Gregory, Ecole Polytechnique, Paris)

La raie de resonance magnétique nucléaire (RMN) du Tellure monocristallin est deplacée de fa~onrelativement importante et fortement anisotrope. Le spectre de R. M. N. possède une

deux ou trois raies suivant l’orientation du monocristal dans le champ magnétique directeur. Nous avons Pu determiner directement Ia partie anisotrope du tenseur de déplacement chimique et ses axes propres. The nuclear magnetic resonance (N.M.R.) line in a single crystal of Tellurium presents a large and strongly anisotropic shift. The N.M.R. spectrum has one, two or three lines depending upon the orientation of the single crystal with respect to the direction of the applied magnetic field. We have been able to determine directly the anisotropic part of the chemical shift tensor and its principal axes. The directions of these axes are given relative to the crystallographic axes. The results are discussed in connection with the crystal symmetries of Tellurium. (Received 24 January 1967)

Brookhaven National Laboratory will organize an International Conference on Solid State Physics Research with Accelerators, to be held at Brookhaven National Laboratory. The meeting will consist of 7 hall-day sessions; each session will include one 45 mm. review paper and three 30 mm. contributions selected from submitted abstracts. The provisional agenda covers electronic interactions (1 day), nuclear and atomic interactions (1 day) and radiationinduced defects 1~days). Attendance will be limited to 125 persons. Abstracts of contributions (not to exceed 200 words) and requests for further information should be sent to: Dr. A. N. Goland Department of Physics Brookhaven National Laboratory Upton, New York -11973
