Abstract

Parity nonconservation (PNC) has been studied in neutron p-wave resonances of ¹¹⁷Sn. The longitudinal asymmetries were measured for 29 p-wave resonances in the neutron energy range 0.8 eV to 1100 eV. Statistically significant PNC effects were observed for four resonances. A statistical analysis determined the rms weak mixing matrix element and the weak spreading width. A weak spreading width of Γ_w=(0.28_-0.15^+0.56)×10^-7 eV was obtained for¹¹⁷Sn.
