PARITY VIOLATION IN CHARGED-PARTICLE RESONANCES

Recent parity nonconservation (PNC) measurements in nuclei use the com pound nucleus as a laboratory for the study of symmetry breaking, with the symmetry breaking matrix elements treated as random variables. Th is approach is made appealing by the observation of very large parity violation in neutron resonances. One key issue is the mass dependence of the effective nucleon-nucleus weak interaction. The neutron measure ments do not appear feasible for light nuclei. We have calculated PNC observables for charged particle resonance reactions for over 100 stat es in five s-d shell nuclides using experimental values of the resonan ce parameters. Analyzing powers show strong dependence on energy and a ngle, and vary greatly from resonance to resonance. Proposed PNC exper iments are discussed.
