Abstract: The TRIPLE Collaboration has performed measurements of the helicity dependence of the neutron resonance cross section for many nuclides. More than 70 statistically significant parity violations have been observed. Generic enhancements amplify the signal for symmetry breaking and the stochastic properties of the compound nucleus permit the strength of the symmetry-breaking interaction to be determined without knowledge of the wave functions of individual states. The measurements are concentrated in the regions of the 3p and 4p maxima of the neutron strength function-near A=110 and A=230. The results to date are summarized. © 2000 American Institute of Physics. [ABSTRACT FROM AUTHOR]
