摘要：

High Purity alpha-Pu 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 B0 of alpha-Pu was determined as 43(2) GPa, with a pressure derivative B0' = 15(2).
