A study of the reaction pi+ + d --> p + p has been performed in the energy range of 18 - 44 MeV. Total cross sections and differential cross sections at six angles have been measured at 15 energies with an energy increment of 1 - 2 MeV. This is the most systematic data set in this energy range. No structure in the energy dependence of the cross section has been observed within the accuracy of this experiment.

MEASUREMENT OF THE DIFFERENTIAL CROSS-SECTIONS FOR THE PI+ D ---> P P REACTION AT PION ENERGIES OF 280-MEV, 300-MEV, 330-MEV, 357-MEV, 390-MEV, 420-MEV AND 450-MEV

Differential cross sections for the process pi +d to pp at seven energies in the region Tpi =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 Tpi . 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 Tpi >or=357 MeV. The total cross sections for the process pi +d to pp are also presented.

The differential cross section for the reaction π + + d → p + p has been measured at pion momenta between 0.48 and 1.16 GeV c with steps of 20 and 40 GeV c for seven CM proton angles between 6° and 61°. At smaller angles, the measured cross sections show a dip at around 0.7 GeV c , while at larger angles the cross sections vary monotonically as a function of incident momentum. The angular distribution shows a considerably rapid variation with increasing momentum. Legendre polynomial fits of the data are presented.

The total cross section and the differential cross sections of the reactions π + d →π + d (elastic scattering) →π + pn (inelastic scattering) →π 0 pp (charge exchange scattering) →γ pp (radiative absorption) → pp , (non-radiative absorption) have been measured using 85 000 pictures of 290 MeV/ c positive pions in the 38 cm Princeton-Pennsylvania bubble chamber. The elastic, inelastic and charge exchange scattering data are more complete than any previous data in this energy range.
