Abstract
Parity nonconservation (PNC) has been studied in neutron p-wave resonances of Sn-117. The longitudinal asymmetries were measured for 29 p-wave resonan ces in the neutron energy range 0.8 eV to 1100 eV. Statistically significan t PNC effects were observed for four resonances. A statistical analysis det ermined the rms weak mixing matrix element and the weak spreading width. A weak spreading width of Gamma (w) = (0.28(-0.15)(+0.56))x10(-7) eV was obta ined for Sn-117.
