The spectra of neutrons with initial energy 14.6 MeV inelastically scattered by the nuclei /sup 23/Na, /sup 27/Al, and /sup 32/S have been measured in coincidence with energetic prompt ..gamma.. rays. Differential cross sections for inelastic scattering are obtained, and also the differential cross sections for the neutron yield. Radiative decay of states with an unbound proton is responsible for 300 mb in the inelastic scattering cross section for /sup 23/Na, 400 mb for /sup 27/Al, and 110 mb for /sup 32/S with a total (n,n'..gamma..) cross section respectively 560, 580, and 270 mb. Cross sections are given for the reactions (n,np) and (n,pn). A calculation of the cross sections according to a statistical model systematically taking into account angular momentum does not give complete agreement with experiment. The observed deviations can be explained by the dominance of certain single-particle configurations in the highly excited nucleus immediately before nucleon emission.
