Abstract
- We present a practical formalism of low-energy nuclear reactions in which the ground-state correlations are treated in the random-phase approximation. The building blocks of the method are the matrix elements of two weakly energy- dependent effective interactions describing particle-hole pair scattering and pair creation or annnihilation in a correlated system. The corresponding transition operator, which give complete information on any nuclear reaction, are then introduced. We apply the method to a study of nucleon scattering, photonuclear, muonuclear reactions proceeding through the 1- states of /sup 16/O. The single-particle basis states are generated by a local, real Woods-Saxon potential, while the residual interuction has a zero range. In the relatively high excitation energy being studied, the correlations retained in the random- phase approximation affect very little nucleon scattering but reduce transition rates in photonuclear reactions and muon capture by about 8%.
