The experimental energy, angular and isotopic distributions for hydrogen and helium nuclei produced in 6.7 GeV deuteron interactions with 58Ni and 64Ni isotopes are presented. The data obtained by using the multichannel E-E semiconductor spectrometer in the 3-50 MeV energy range. Energy spectra are very close to Maxwell distribution, angular distributions are isotropic, isotopic ratios do not depend on emission angle of fragments but depend on a projectile mass

The tensor analyzing power T 20 for the reaction d ↑ + 12 C → π ± (0°) + X has been measured with a polarized deuteron beam from 6.2 to 9.0 GeV/ c at a pion momentum3.0 GeV/ c . This experiment is focused on “cumulatively produced pions”, which are produced beyond the kinematically allowed limit for free nucleon-nucleon collisions. The measured values of T 20 turn out to be close to zero. They are in disagreement with the results of our impulse approximation calculation which is based on a single NN → πNN interaction and takes into account the internal motion of nucleons in the deuteron. Possible explanations of the result are discussed.
