With observation angles of 29° and 46° relative to a proton beam there were obtained energy spectra for the production of charged rr-mesons in the process p+ p->rr+, Differential cross sections were measured for the angles of 29°, 46° and 65° in the laboratory system.

The rr- + p- n + rr0 charge-exchange scattering and the rr- + p- n + 1J ( 1J- 2y) reaction were investigated in 1.55-4.5 BeVIc region in a 17-liter propane-xenon bubble chamber. The total cross sections of both reactions were measured in this region. The angular distributions of the rr0 mesons in the charge-exchange reaction were obtained. The backward exchange-scattering cross sections du( rr- + p- n + rr 0 )ldQ were estimated.

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.
