Microscopic description of the absorption of bound pions

Abstract

The absorption rates of bound 1s and 2p pions in some light nuclei have been investigated on the basis of a shell model picture modified by short range nucleonnucleon correlations. It turns out that the total absorption rate, the missing energy spectra and the single neutron energy spectra depend sensitively on the details of the correlation functions. The results of the present analysis indicate that one can obtain informations on the short range correlations from pion absorption experiments.
