Abstract

Coincidence measurements of (p,n) reactions at 1.5 GeV/c in the excitation region have been carried out for the first time. The location of the peak in the neutron spectrum is found to be dependent on the coincident particles. The peak in coincidence with p+ is shifted to lower momenta compared to the free case, in contrast to the inclusive spectrum and the coincidence with other particles where it is shifted to higher momenta. The p+ invariant-mass distribution for C is significantly lower and broader than that for H. The coincidence data set stringent constraints on theoretical models introduced to interpret the peak shift in inclusive spectra.
