Abstract

The reactions H3(He3, d)He4, H3(He3, p)He5 and H3(He3, p)He4, n1 have been studied in the 100-kev to 800-kev region of bombarding energy. In the case of H3(He3, p)He5, the proton energy was measured with a scintillation spectrometer; from this measurement, the energy of breakup of He5 into a neutron and an α particle was found to be 0.95±0.07 Mev. At a bombarding energy of 360 kev, the deuterons from the H3(He3, d)He4 were found to be isotropic in the center-of-mass system. The spectrum of protons from the three-body breakup, H3(He3, p)He4, n1, was found to be flat within experimental error from 2 to 8 Mev. Competitions among the various modes of decay of the compound nucleus of Li6 do not vary beyond an experimental uncertainty of ±2 percent from 200-kev to 600-kev bombarding energy. The shape of the total cross-section curve, measured from 100 kev to 800 kev, appears to indicate a nonresonant behavior, similar to the case of the dd reaction.
