IDENTIFICATION AND YIELD OF PD117 IN THE THERMAL-NEUTRON FISSION OF U235
Abstract
As part of a study of nuclear charge distribution in the region of symmetric fission, the existence and cumulative fission yield of 117Pd were sought. Palladium was isolated free from silver and cadmium at different times after fission and the quantity of descendant 117Cd activity was measured. A half-life for 117Pd of 5.0 +0.5 or -0.7 sec was derived from these data. Through a comparison of 117Cd activity produced by 117Pd with the total 117Cd activity produced by all isobars, a cumulative fractional chain yield of 0.682 was computed for 117Pd. From this yield the most probable nuclear charge (Zp) for the 117-mass chain was estimated.
