Abstract

We present an analysis of π±C12 elastic scattering by using a phenomenological ansatz for the pure hadronic amplitude; in addition a careful treatment of Coulomb effects has turned out to be essential. The resulting phase shifts and inelasticity parameters show a smooth behavior in the entire energy region between Tπ=30 and 230 MeV. The rapid increase of the differential cross sections at backward angles (Tπ=162 MeV) is discussed in terms of a semiclassical theory of the nuclear glory effect and is well reproduced by using additional information on analytic structure of the πC12 elastic scattering amplitude in the complex t plane.
