HALF-LIFE MEASUREMENTS OF SOME NEUTRON INDUCED ISOMERS.
Abstract
Half-lives of thermal neutron activated isomers were determined by direct decay measurements with a scintillation counter. Scaler pulses following a single channel analyzer, together with precise timing pulses, were traced concurrently by a fast chart recorder. The gain stability of the detecting circuit was also monitored during the decay period. Decay counts were corrected for counting circuit dead-time and for pulse pile-up, and analyzed by a digital computer. The average half-lives obtained, together with their statistical uncertainties are: Hf178m 3.79 = 0.07 sec., Hf179m 18.18 = 0.28 sec., Yb177m 6.40 = 0.02 sec., W183m 5.14 = 0.02 sec. (Author)
