Curium-berkelium alloys were studied by X-ray diffraction up to 53 GPa to probe their structural behaviour under pressure. Two different alloy compositions were studied successfully in this work: one was a Cm(0.70)-Bk(0.30) alloy and the second was a Cm(0.46)-Bk(0.54) alloy. The goal was to understand the phase and relative volume behaviour of both alloys in terms of bonding, the elements' electronic configurations, and their pressure behaviour relative to that reported for the pure Am-Cf metals. Given here are the results of the high-pressure studies of these Cm-Bk alloys, and a discussion of the significance of the findings with respect to the published actinide pressure-phase diagram.
