New look at the atomic volumes of the. beta. -form of the transplutonium metals

Conference ·
OSTI ID:5535301
The atomic volumes of the beta-form of the first four transplutonium metals were evaluated using data for samples prepared by thermal and by pressure treatment. The volumes derived for curium, berkelium, and californium metals quenched from elevated temperatures were found to be consistently larger than those for ''pressure-quenched'' samples, whose volumes were in good agreement with values for the alpha-forms. The cubic lattice parameters from ''pressure-quenched'' samples also provided a more consistent trend than those obtained from thermally quenched samples when compared to the parameters for the mononitrides of the metals.
