Multinucleon emission following the pion absorption in N, Ar and Xe

Positive pion absorption was studied in an almost 4p geometry allowing simultaneous measurements of various charge and neutral multiplicities. Total absorption cross sections and its decomposition into the most important channels is determined. The results are presented for N, Ar and Xe nuclei at incident pion energies of 118,162 and 239 MeV. The role of multinucleon emission in the absorption process is emphasized

Pion absorption in ^4He

This paper presents a large solid angle measurement of the positive pion absorption cross section on ^4He and its decomposition into partial channels. A large fraction of the absorption cross section at incident pion kinetic energies of T_π+ =70, 118, 162, 239, and 330 MeV is due to multinucleon channels
