RADIATIVE PION CAPTURE IN NUCLEI - A CONTINUUM SHELL-MODEL APPROACH

The radiative pion capture process in nuclei is approached by using a continuum shell-model description of the nucleus, together with a phen omenological treatment of the two particle-two hole effects. It is fou nd 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-f ield potential. This makes this process interesting to investigate the nuclear structure dynamics.
