Pion Absorption at 1 GeV/c
The first experiments concerning pion absorption at 1 GeV/c on 4He and 12C targets have been performed. Both the (π+pp) and (π+, pn) modes were measured and two-nucleon absorption events were clearly observed. A preliminary analysis shows a large difference in the isospin dependence of the process from that of ∆-esonance region.
