Excited states of Li^6 observed through He^4(d, d)He^4

Abstract

Angular distributions (18° ≦ θ_(c.m.) ≦156 °) for the elastic scattering of deuterons from He4 have been obtained at 500 keV intervals for bombarding energies between 2.9 and 11.5 MeV. A phase shift analysis of these data has been made yielding confirming evidence for the existence of D wave, J^π = 2^+ and 1^+ levels at excitation energies of 4.9 and 6.2 MeV, respectively. Single-level analyses of the P wave phase shifts indicate the possible presence of 2^−, 1^− and 0^− levels at 6.8, 7.8 and 9 MeV excitation energies. The moments of the tensor polarization of the scattered deuterons have been calculated and are compared to recent experimental results. The total reaction cross section is also calculated and is found to be in fair agreement with experiment.
