摘要：

We examine the scattering of charged pions from the trinucleon system at a pion energy of 180 MeV. The motivation for this study is the structure seen in the experimental angular distribution of back-angle scattering for pi(+)-He-3 and pi(-)-H-3 but for neither pi(-)-He-3 nor pi(+)-H-3. We consider the addition of a double spin flip term to an optical model treatment and find that, though the contribution of this term is non-negligible at large angles for pi(+)-He-3 and pi(-)-H-3, it does not reproduce the structure seen in the experiment. [S0556-2813(99)02003-8].
