The angular distributions of high-energy deuterons and proton-deuteron coincident events were measured at Tπ = 65 MeV for C, Al and Cu. The angular distribution of the inclusive (π+, d) cross section was similar to that of the inclusive (π+, p?) reaction, but the ratios of the inclusive (π+, pd?) cross section to the inclusive (π+, pp) cross section had a strong angular dependence. These results support the idea that contributions from the three-nucleon absorption as well as those from the two-step process are important for the emission of high energy deuterons at Tπ = 65 MeV.
