Measurements of the invariant cross sections for the reaction p(400 GeV)+(Li6, Be,C,Al,Cu,Ta)→(d, t, He3, He4)+X at laboratory angles of 70, 90, 118, 137, and 160° are reported. Comparisons are made using several scaling variables. NUCLEAR REACTIONS Inclusive cross section; 400 GeV incident protons; Li6, Be, C, Al, Cu, Ta targets; production of d, t, He3, He4; Lab angles 70°, 90°, 118°, 137°, and 160°.

The charge-exchange cross sections were measured for π − on Li, C, Al and Cu nuclei at momentum 48 GeV/ c . By comparing the data obtained for nuclei with those for hydrogen under the same conditions the effective numbers of protons are defined. The conclusion is made that η 0 mesons are absorbed in nuclei weaker then π 0 . The total cross section of η 0 interactions with the nucleon is determined to be σ tot ( η 0 N) = 15 ± 5 mb in agre ement with the quark model.

The angular and energy distributions of pions produced by 650-MeV protons and pion-nucleon correlations were studied using a liquid hydrogen bubble chamber. The present investigation indicates that the experimental angular distributions of neutral and charged pions are consis- tent with the assumption of isotopic spin conservation. The contributions of rrN subsystem states with isospin T 11'N = 7' 2 and % are measured; the contribution of the latter is 72 ± 3%.

The mass spectrum of 3γ states produced in π−p collisions has been studied. A peak corresponding to ωo→πoγ decay in the π−p→ωon reaction was selected. The measurements were performed at the IHEP accelerator at momenta 21, 25, 32.5, 40 and 48 GeV/c. The reaction cross section decreases with the momentum in a power form (∼P−2.4) The differential cross section follows exponential t-dependence, exp (bt). The scattering cone shrinks slowly with the energy increase.
