The energy distributions of alpha particles and of protons from the He/ sup 3/ + t reactions have been measured for 1.9-Mev incident tritons at laboratory angles of 30 deg for alphas, and both 30 deg and 90 deg for protons. Absolute cross sections are obtained. The spectra are discussed in terms of a model which assumes that uncorrelated three-body breakup and several two-stage processes all contribute independently to the cross section. The calculations based on this model are in excellent agreement with the observed spectral shapes. The neutron-proton correlation corresponding to the unbound singlet state of the deuteron is observed. The binding energy of He/sup 5/ (for breakup into a neutron and an alpha particle) was found to be epsilon = -0.79 plus or minus 0.03 Mev. (auth) |
