The (π+,pd) and (π+,dd) reactions on light nuclei at 100 and 165 MeV incident pion energies

Abstract

The (π + , pd), and (π + , dd) reactions were investigated with pions of 100 and 165 MeV kinetic energy on 6 Li and 12 C targets. In comparison with previously published (π + , pp) data on the same targets and at the same beam energies, kinematic regions were identified in which the neutron pickup process n+p → d dominated the observed deuteron yield. The importance of this mechanism increases with energy, contributing half of the observed cross section at 165 MeV. The contribution of direct quasi-triton absorption is significant only at 100 MeV.25.80. Ls,25.80.Hp,25.10.+s
