    "abstract": "We examine the scattering of charged pions from the trinucleon system at a\npion energy of 180 MeV. The motivation for this study is the structure seen in\nthe experimental angular distribution of back-angle scattering for pi+ 3He and\npi- 3H but for neither pi- 3He nor pi+ 3H. We consider the addition of a double\nspin flip term to an optical model treatment and find that, though the\ncontribution of this term is non-negligible at large angles for pi+ 3He and pi-\n3H, it does not reproduce the structure seen in the experiment.",
