X-ray diffraction studies of AuCu3-type neptunium compounds under pressure
摘要:
NpX3 (AuCu3-type structure) compounds with X=Al, Ga, Ge, In and Sn were studied up to 50 GPa using the energy dispersive X-ray diffraction (EDXRD) technique. No structural phase transitions were observed for any of the compounds studied up to the highest pressures attained. The compressibility was measured for each compound and compared with theory. The results for NpX3 are compared with those previously obtained for UX3. (C) 2000 Published by Elsevier Science S.A. All rights reserved.
