abstract
Parity nonconservation (PNC) was studied in p-wave resonances in Ag by measuring the helicity dependence of the neutron total cross section. Transmission measurements on natural Ag were performed in the energy range 32 to 422 eV with the time-of-flight method at the Manuel Lujan Neutron Scattering Center at Los Alamos National Laboratory. A total of 15 p-wave neutron resonances were studied in 107Ag and nine p-wave resonances in 109Ag. Statistically significant asymmetries were observed for eight resonances in 107Ag and for four resonances in 109Ag. An analysis treating the PNC matrix elements as random variables yields a weak spreading width of Γw = (2.67+2.65-1.21) × 10-7 eV for 107Ag and Γw = (1.30+2.49-0.74) × 10-7 eV for 109Ag.
