摘要：

We show that the pi+-3 He asymmetry data obtained in a recent TRIUMF experiment at T(pi) = 100 MeV can be understood in terms of the elementary pi-N amplitudes. Through a comparison to a full optical-potential calculation that employs realistic Faddeev wave functions for the trinucleon we show that all nuclear-structure dependence cancels for A(y) at lower energies. At higher pion energies around the DELTA-resonance region the sign flip of A(y) offers the possibility of extracting information about the smaller partial waves.
