Absolute total and differential cross sections for the reaction x + +d-+ p+p have been measured for pion energies from 3.7 to 20.5 MeV. Evidence for p-wave strength was observed for all energies. Using detailed balance and corrections for Coulomb effects, the measured differential and total cross sections were found to be consistent with recent measurements for the reaction n+p-^d + n 0 , offering no evidence for charge-independence breaking. The measured total cross sections for energies below 30 MeV are in disagreement with predictions by Blankleider and by Vogelzang, Bakker, and Boersma.
Absolute total and differential cross sections for the reaction sr+ + d -+ p+ p have been measured for pion energies from 3.7 to 20.5 MeV. A crossed-field velocity separator was used to enhance the purity of the pion beam, and a deuterated scintillator was used both as the target and to count the incident Aux. The total cross sections are 4.0 + 0.5, 4.4 + 0.2, 4.2 + 0.2, 4.2 + 0.2, and 4.8 + 0.3 mb for incident pion energies of 3.7, 5.0, 9.6, 15.2, and 20.5 MeV, respectively. The measured difFerential cross sections indicate the presence of p-wave strength at all energies studied and are in good agreement with recent measurements for the reaction n+ p~d + n' near threshold and a recent parametrization of the total and difFerential cross sections for the process.
