Calculation of Nuclear Reactions in ^{16}O in the RandomPhase Approximation
Abstract
We present a practical formalism of lowenergy nuclear reactions in which the groundstate correlations are treated in the randomphase approximation. The building blocks of the method are the matrix elements of two weakly energydependent effective interactions describing particlehole pair scattering and pair creation or annnihilation in a correlated system. The corresponding transition operators, 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 ^{16}O. The singleparticle basis states are generated by a local, real WoodsSaxon potential, while the residual interaction has a zero range. In the relatively high excitation energy being studied, the correlations retained in the randomphase approximation affect very little nucleon scattering but reduce transition rates in photonuclear reactions and muon capture by about 8%.
