Samples of intermetallic compounds Pt/sub 5//sup 249/Cf and Pt/sub 5//sup 249/Bk were obtained in the form of thin layers on a platinum support. It was found that the Pt/sub 5/Bk and Pt/sub 5/Cf intermetallides have a hexagonal structure of the Cu/sub 5/Ca type with parameters: a = 0.5270 +/- 0.0005, c = 0.4423 +/- 0.0004 for Pt/sub 5/Bk and a = 0.5266 +/- 0.0008, c = 0.4420 +/- 0.0005 nm for Pt/sub 5/Cf. The x-ray amorphization of the crystal lattice of the Pt/sub 5/Cf intermetallide was discovered after approx. 70 days of holding at room temperature, and its restoration after short-term annealing at 500/sup 0/C in vacuo. It was found that lattice parameters and volume of the unit cell of Pt/sub 5/Bk intermetallide increases after approx. 140 days of holding. This is due to the accumulation of /sup 249/Cf as the result of ..beta..-decay of /sup 249/Bk and the corresponding increase in the ..cap alpha..-activity of the sample.
