Abstract
The distributions of protons after the absorption of positive pions by He-3 at 118, 162 and 239 MeV are presented. A decomposition of the th ree-nucleon cross section in terms of initial state interactions acid other processes is given, based upon simple models. A clear signal of initial state interactions is visible in the data, diminishing at the lower energies.
