Abstract
For nearly 100 nuclei, the rms expectation values of three neutron transmission observables sensitive to parity violation are predicted. Total enhancement factors {similar to}10{sup 2--}10{sup 4} in comparison to related observables in nucleon-nucleon scattering are found. To this end, a model of parity violation in the framework of statistical scattering theory is formulated and worked out in detail. General expressions are deduced from it, which connect the expectation values of parity forbidden {ital S}-matrix elements to average input parameters, namely, level densities, transmission coefficients, and spreading widths. The general results are discussed in terms of the relevant nuclear time scales, and the numerical predictions in terms of a parity forbidden strength function'' and several enhancement factors. Additionally, the role of finite energy resolution, crucial for energy averaging experiments, is studied.
