[en] Angular distributions of differential cross sections were measured for the first time for pion absorption on a T = 1, S = 0 nucleon pair and for absorption on a T = 0, S = 1 pair in the ³He nucleus. A large isospin dependence is observed in the differential cross sections. The ratio of cross sections sigma(³He(π⁺,2p))/sigma( ³He(π^-,pn)) is 15.3 +- 1.2. The results show evidence of an isoscalar component of the final state in the reaction ³He(π^-,pn)n, which cannot be mediated by Δ resonance formation
