[en] Parity non-conservation was studied for seventeen states in the compound nucleus 239U by measuring the helicity dependence of the p-wave resonance cross section for epithermal neutrons scattered from 238U. The root-mean-squared parity-violating matrix element for the mixing of p-wave and s-wave states was determined to be M = 0.58-0.25+0.50 meV. This corresponds to a parity-violating spreading width of ΓPV = 1.0 x 10-7 eV. This gives a value of 4 x 10-7 for αp, the ratio of strengths of the P-odd and P-even effective nucleon-nucleon interactions in 239U. In this paper the implications of these results for studies of Time Reversal Symmetry in the compound nucleus is discussed
