Title: Chemical consequences of radioactive decay. 2. Spectrophotometric study of the ingrowth of berkelium-249 and californium-249 into halides of einsteinium-253

The ingrowth of /sup 249/Bk daughter and /sup 249/Cf granddaughter into fluorides, chlorides, bromides, and iodides of parent /sup 253/Es was followed by spectrophotometric methods. In the case of trivalent Es halides, the oxidation state of the parent is maintained by its progeny. In the case of divalent Es halides, the oxidation state of the parent is retained by the granddaughter species. No other oxidation states or chemical species of the progeny ions are observed even though experimental conditions of storage such as physical state, temperature, or cover-gas composition were varied. These results are considered in terms of mechanisms that would allow such chemical stability.
