Abstract

Parity nonconservation was studied for 23 p-wave resonances in ¹¹³Cd up to E_n=500eV 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 M_J=1=2.9_-0.9^+1.3meV 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.
