Study of the inclusive inelastic scattering of 100-MeV pions from /sup 2/H, /sup 3/He, and /sup 4/He
Measurements were carried out of the double-differential cross sections of 100 MeV positive and negative pions inelastically scattered from /sup 2/H, /sup 3/He and /sup 4/He. Inclusive spectra and angular distributions of the scattered pions from the (..pi..,..pi..') reaction were obtained at several angles for the three targets using a magnetic spectrometer. The yields of the scattered pions from /sup 2/H, /sup 3/He, and /sup 4/He were normalized to measured /sup 1/H scattering data and to the known ..pi../sup +/ N cross sections in the literature. The angular distributions of 100 MeV pions scattered from /sup 2/H, /sup 4/He and /sup 4/He at the back angles (Theta/sub lab/ greater than or equal to 75/sup 0/) were found to have very nearly the same shape as the free ..pi../sup +/-p distribution at this energy. The ratios of the energy- and angle-integrated ..pi../sup +/ inelastic scattering cross sections at the back angles compared to the free ..pi../sup +/-p cross sections were found to be 0.69 +/- 0.03 for /sup 2/H, 1.42 +/- 0.06 for /sup 3/He, and 0.88 +/- 0.03 for /sup 4/He.
