Abstract
The main aim of this work is the construction of a first-order optical potential for the scattering of pions by {sup 3}He at low energy with as few approximations as possible. In particular the Fermi motion is treated extremely carefully by using microscopic {sup 3}He wave functions and by performing the complete Fermi-integral. Differential cross-sections and analyzing powers have been calculated. In a detailed comparison between the first-order optical with one which results from using the semi-factored approximation, it became clear that the latter has the following shortcomings: 1. the dependence of the subenergy on the pion-nucleus scattering angle, and 2. the independence of this energy on the relative motion of the spectator nucleons. (author). 101 refs.; 15 figs.; 3 tabs.
