Abstract

Pu245 and Am245 were prepared by neutron irradiation of Pu244. The beta-decay half-lives of Pu245 and Am245 were found to be 10·1 ± 0·5 hours and 119 ± 1 minutes, respectively. The beta-decay energy of Am245 was found to be 0·86 MeV by absorption methods, and γ-rays of 260, 121, and 70 keV∗ were resolved with a sodium iodide crystal spectrometer. The thermal neutron capture cross-section of Pu244 was determined to be 1·4 barns.
