Two nucleon emission following bound pion absorption

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

The absorption of a bound 2p pion in16O with the emission of two fast nucleons leading to low excitation of the residual nucleus has been studied. In our calculation, the following important effects have been considered simultaneously: (i) correlations in the initial nuclear wave function are treated on the basis of the Brueckner theory, (ii) the mutual final state scattering of the emitted pair and (iii) the nucleon-nucleus scattering are taken into account by the use of eikonal model wave function. Results are compared with other calculations and experiments. It is found that inspite of our elaborate treatments serious discrepancies between theory and experiments still remain. A more careful study of the absorption mechanism is emphasized.
