Abstract

Reactions initiated by Li7+Li6 have been studied at six bombarding energies between 3.78 and 5.95 MeV. A dEdxE system was used for particle detection and identification, and an on-line computer was utilized for pulse-height analysis, storage, and data analysis. Differential and total cross sections were obtained for protons leading to the 0.0, 0.95, 1.67, 2.62-2.72, and 3.39-MeV levels of B12; deuterons leading to the 0.0, 2.14, 4.46, 5.03, 6.76-6.81, and 7.30-MeV levels of B11; tritons leading to the 0.0 and 0.717-MeV B10 levels; and alphas leading to the Be9 ground state. The dominant reaction process appears to be the transfer of an α particle, as evidenced by the angular distributions and total cross sections for B10 and B11 levels. In all cases, the total cross sections are generally smoothly increasing over the observed energy range with no evidence for structure. The proton cross sections have the lowest magnitude of the particles observed here, and a compound-nucleus process seems most likely for those groups.
