The {ital p}+{ital p}{r_arrow}{pi}{sup +}+{ital d} reaction is studied at excess energies between 0.275 and 3.86 MeV. Differential and total cross section were measured employing a magnetic spectrometer with nearly 4{pi} acceptance in the center of mass system. The measured anisotropies between 0.008 and 0.29 indicate that the {ital p} wave is not negligible even so close to threshold. The data are compared to other data offering no evidence for charge symmetry breaking or time reversal violation. The {ital s}-wave and {ital p}-wave contributions at threshold are deduced. {copyright} {ital 1996 The American Physical Society.}
