Abstract

Berkelium and californium were studied by x-ray diffraction up to pressures of 57 GPa (Bk) and 48 GPa (Cf). Participation of the 5f electrons in the metallic bonding, as evidenced by the appearance of the low symmetry alpha uranium structure and by a sudden volume decrease, starts at about 25 GPa in berkelium and at 41 GPa in californium.
