| Abstract: | Osmium isotope, 197Os, produced with 14 MeV neutrons through the reaction of 198Pt(n,2p)197Os, has been identified and its decay properties have been studied with a g(X) spectroscopic method. The ten new g-rays of 41.2, 50.7, 196.8, 199.6, 223.9, 233.1, 250.2, 342.1, 403.6, and 406.4 keV assigned to the decay of 197Os were observed. The half-life of 197Os has been determined as 2.8±0.6 minutes. A partial decay scheme of 197Os was proposed. |
