Neutrons from the interaction of ..pi../sup -/ at rest in /sup 28/Si were measured in coincidence with ..gamma.. rays which provided the identification of the resulting nuclei. Neutron energy spectra and neutron multiplicities were derived in discrete channels. A comparison is made with the interaction of 70 MeV ..pi../sup +/ with the same target investigated by proton-gamma coincidences. Despite their low detection efficiency, neutrons give information as valuable as protons and are an even better tool in the low-energy region under the experimental conditions. They give access to the study of all the secondary processes of the pion absorption.
