Evidence for M1 strength in the (p3,)4He reaction


Journal Article

Angular distributions of cross sections and analyzing powers were measured for the H3(p,)4He reaction at incident proton energies of 2.0, 5.0, and 9.0 MeV. The 90°analyzing power was measured at 11 energies between 0.8 and 9.0 MeV. A transition matrix element analysis indicated that the inclusion of M1 strength gave better fits and eliminated the anomalously large D23 (E2) strength reported in earlier work. An E1-plus-E2 direct capture calculation was performed. It is shown that this calculation can be brought into agreement with the data if an M1 strength comparable to that found in the T-matrix element analysis (0.51.0% of the total capture cross section) is added. © 1989 The American Physical Society.
