Measurement of the differential cross sections for the π ⁺d→pp reaction at pion energies of 280, 300, 330, 357, 390, 420 and 450 MeV

Differential cross sections for the process pi ⁺d to pp at seven energies in the region T_pi =280-450 MeV and in the angular range theta * approximately=4-90 degrees have been measured on the LNPI synchrocyclotron. The results include 94 new data points. The measurements have been carried out using a ten-channel hodoscope set-up. Statistical errors are between 2.5% and 7.8% depending on the scattering angle and T_pi . The data obtained indicate that there is an essential contribution from the partial wave with orbital angular momentum l=3 over the whole energy range considered. The authors also observe a noticeable contribution from the l=4 partial wave to the differential cross sections of the pi ⁺d to pp reaction from T_pi >or=357 MeV. The total cross sections for the process pi ⁺d to pp are also presented.
