Abstract:

The formation of Pd115 in thermal neutron fission of U235 was studied quantitatively. A procedure was developed which rapidly separated palladium from daughter elements silver and cadmium. Separations were made from 2.8-120 seconds after fission. The growth of Cd115 from palladium separated at various times constituted a decay curve for Pd115. The half-life thus determined was 40.5,-3.0 seconds, a value which agrees with that previously reported. The cumulative fractional yield of Pd115 compared to the total Cd115 yield was 90.5 7.2 . Estimation of the most probable nuclear charge must await information on the contribution of other members to the yield of the 115 mass chain.
