Abstract
Electrodepositions of californium isotopes were successfully performed at Oak Ridge National Laboratory involving two different types of deposition solutions, ammonium acetate and isobutanol. A californium product that was decay-enriched in 251Cf was recovered for use in super-heavy element research. The californium was purified and then electrodeposited using the isobutanol method onto thin titanium foils for use at the Joint Institute for Nuclear Research. An ammonium acetate method was used to produce a deposition containing 1.7 ± 0.1 Ci of 252Cf onto a stainless steel substrate. This is the largest single electrodeposition of 252Cf ever prepared.
