Abstract The following half-lives were measured: B/sup 1//sup 2/ 20.31 plus or minus 0.20 msec; the 472 kev level of Nail, 19.9 plus or minus 0.3 msec; and the 305 kev level of As/sup 7//sup 5/, 16.8 plus or minus 0.4 msec. The activities were produced by a pulsed beam from a Van de Graaff generator. The data were taken with gated radiationdetection circuits in conjunction with a time- delay analyzer, and the half-lives were determined by least-squares analysis. (auth)
