Abstract

The radiative pion capture process in nuclei is approached by using a continuum shell-model description of the nucleus, together with a phenomenological treatment of the two particle-two hole effects. It is found that these effects play an important role to reproduce the observed experimental photon energy distribution. This distribution as well as the integrated one depends significantly on the details of the mean-field potential. This makes this process interesting to investigate the nuclear structure dynamics.

      There is an abundant literature in the field, and we do not aim at performing an exhaustive comparison, but we will rather focus in some representative works, where RPA or SF effects have been examined. Even though one may expect that in the low energy regime (excitations below 50 MeV) the LFG based formalism should break down, it was argued in [121,122] that the current scheme gives reasonable estimates for inclusive (integrated) quantities, for instance inclusive muon and radiative pion capture widths in nuclei. Thus, the shapes of the differential cross sections or widths which will be presented in this subsection do not pretend to recover the physical spectra (which might contain discrete transitions and/or resonances in this energy range).
