Tensor polarization of 6Li ∗ (2.186 MeV, 3 +) in the 9Be(p,α) 6Li reaction at 40 MeV

Abstract

Tensor moments t kq have been determined for the 6Li ∗ (2.186 MeV, 3 +) state produced in the 9Be(p,α 1) 6Li reaction at 40 MeV. Angular correlation measurements were made between α 1 and the α-particle or deuteron fragment from the breakup of 6Li ∗. Comparison of the t kq are made with the predictions of a model that includes direct and exchange processes. Angular distributions of the differential cross sections for the 9Be(p,α) 6Li reaction for the g.s. and first two excited states are presented.
