Pressure-induced phase transition in alpha-Pu
High purity alpha plutonium was studied by X-ray diffraction in a diamond anvil cell up to 62 GPa. A structural phase transition occurs around 40 GPa. The high pressure structure was indexed in a hexagonal lattice of space group P6(3)/m, a = 537.77 pm, c = 445.51 pm at 62 GPa, Z = 8. The bulk modulus B(0) of alpha plutonium was determined as 43(2) GPa, with a pressure derivative B'(0) = 15(2).
