| Abstract |
Parity nonconservation (PNC) was studied for 24 p-wave neutron resonances in 238U from 10 to 300 eV by measuring the helicity dependence of the total neutron cross section with an improved experimental apparatus. Six resonances show statistically significant (greater than 2.9σ) parity violation. An analysis treating the PNC matrix elements as random variables yields a root-mean-square PNC matrix element M = 0.67-0.24-0.16 meV. The corresponding weak spreading width Γw = (1.35+0.97-0.64)×10-7 eV.
