Abstract

Parity nonconservation was studied for 23 p-wave resonances in 113Cd up to En = 500 eV at the LANSCE pulsed neutron source using a longitudinally polarized neutron beam and the time-of-flight method. The helicity dependence of the total neutron capture cross section was measured with an enriched 113Cd target and with a target of natural cadmium. Parity violating effects were observed for several resonances in 113Cd and 111Cd. A root-mean-square value of the parity nonconserving matrix element MJ=1 = 2.9+1.3-0.9 meV was obtained for the spin J=1 levels in the compound nucleus 114Cd. This result from the 3p-peak region of the neutron strength function is compared with the parity violation results for nuclei from the 4p-peak region.
