Angular distributions of the 6 Li (π + , 3 He ) 3 He differential cross section are presented for incident pion beam energies of 60, 80 and 100 MeV, together with a few values at 140 MeV. The results are compared with previously published data and two theoretical predictions. The 60, 80 and 100 MeV data, and previously published results for 15.4 MeV, were fit to Legendre polynomials. The fitted coefficients, which allow the energy dependence of the total and differential cross sections at a fixed c.m. angle to be determined, are also presented. These coefficients show the increasing importance of higher-order partial-waves with increasing pion energy. |
