Experiments on the nuclear interactions of pions

The status of the following experiments is briefly reported: π+ + d → 2p; pion elastic scattering on deuterium; pion elastic and quasielastic scattering from 3He and 4He; pion double charge exchange in He isotopes; measurement of the ratio sigma (12C(π+,π+p)/sigma(12Cπ-,π-p)11B); quasi-elastic scattering of pions on carbon; and coincidence measurements of the reactions 12C(π+-,π+-d)10B and 12C(π+-,π+-t)9B. Several other experiments are proposed. This document is primarily administrative in nature; references are given to completed work. Cross sections are shown, however, for pion scattering from He isotopes at 50 and 200 MeV. 5 figures
