Spectrophotometric and x-ray powder diffraction methods have been applied to a study of the ingrowth of californium-249 by ..beta../sup -/ decay of berkelium-249 in crystalline /sup 249/BkBr/sub 3/. It was found that the Cf daughter grows in with the same oxidation state and crystal structure as the parent. Thus, six-coordinate BkBr/sub 3/ (AlCl/sub 3/-type monoclinic structure) generates six-coordinate CfBr/sub 3/, and eight-coordinate BkBr/sub 3/ (PuBr/sub 3/-type orthorhombic structure) generates eight-coordinate CfBr/sub 3/, a previously unknown form of CfBr/sub 3/. It was also found that the daughter Cf(III) in the BkBr/sub 3/ parent compound can be reduced to Cf(II) by treatment with H/sub 2/, as it can in pure CfBr/sub 3/. 5 figures.
