Correlation measurements of light charged particles emitted from 32S+27Al reactions at energies of 105 MeV and 215 MeV.

Abstract

Previous work has examined light particle correlations from O+Al reactions over a range of energies within a framework of statistical emission from a composite source. The source of these light particles was assumed to be an excited composite nucleus because the excitation energy of the source was not so high that exotic processes such as fragmentation or preequilibrium emission were significant. In this Brief Report we examine correlation functions between light charged particles emitted from reactions of S+Al at 105 MeV and 215 MeV. As in previous work, the proton-proton and proton-deuteron correlations are well described by the results of Monte Carlo simulations based on statistical emission. In this Brief Report we will also compare the results of alpha-alpha and deuteron-alpha correlations to the predictions of models which include the emission of heavier unstable particles (such as {sup 8}Be and {sup 6}Li{sup *}) from the excited source. The results presented here can serve as additional validation of the correlation technique and also as tests of the statistical model.
