3He(p-->,π+)4He reaction near threshold
Abstract
Angular distributions of the differential cross section and analyzing power for the reaction 3He(p,π+)4He have been measured at Tp=178 and 198 MeV. The analyzing powers, which have not been measured previously in the near threshold region, are similar to those of the elementary pp-->π+d reaction at low energies reflecting the dominance of the two-nucleon reaction mechanism.
