At/sup 212/ was produced by the Bi/sup 209/( alpha ,n)At/sup 212/ reaction by bombarding Bi/sup 209/ with a beam of 19-Mev helium ions from the Purdue cyciotron. The At/sup 212/ was observed to decay by alpha emission with a half life of 0.20 plus or minus 0.04 sec. The kinetic energy of the alpha particles emitted in the decay was measured using Au-Si surface-barrier charged particle spectrometers. The alpha-decay energy was found to be 7.87 plus or minus 0.07 Mev. The relative excitation function of the r-ofmass energy range from 17.87 to 18,86 Mev. The hindrance factor for the At/sup 212/ decay is calculated using the experimentally measured At/sup 212/ alpha-decay energy. (auth)
