Description

It is shown that the effects of the nuclear medium on the pion propagator and the renormalization of the πNN interaction, described in terms of excitation of virtual isobar-hole pairs can enhance the predicted absorption rates for pions at threshold to values close to the empirical ones. (orig.)
