Antiproton- 3 He annihilation events at rest have been detected using a self-shunted streamer chamber. The ratio of the cross section for annihilation on neutrons and on protons has been measured (0.467 ± 0.035). It is compared with other results from annihilation on free nucleons, deuterium, 3 He and 4 He. The low value of the ratio seems to indicate a strong isospin dependence of the antinucleon-nucleon P-wave amplitude.

The analysis is based upon p̄Ne annihilation events at rest and at 607 MeV/c detected with a self-shunted streamer chamber exposed to the LEAR beams. The main measured quantities are the following: charged-prong multiplicity, negative pion multiplicity; momentum, angular and rapidity distributions. General distributions are given as well as distributions as functions of charged prong multiplicity. A correlation is found between high multiplicity and depth of the annihilation point. The data are compared with recent theoretical analyses.

The antiproton-helium reaction cross section has been measured at 19.6 and 48.7 MeV with a streamer chamber in a magnetic field. Charged prongs and negative pion multiplicities and cross sections for the production of 3 He are given. A comparison with p 2 H is performed. he previously obtained 179.6 MeV results are also taken into account.

Total inclusive cross sections for rho0, ω and f (1270) meson production and the corresponding average multiplicities < n(rho0) > = 0.072+-0.019, < n(ω) > = 0.033+-0.022, < n(f) > = 0 01 +-0.010 have been measured in π-C interactions at 5 GeV/c. It is shown that approximately 8 percent of secondary π- mesons are produced from the meson resonance decay. For the reactions with the production of rho0 mesons the dependence of the inclusive differential cross sections on the rapidity and squared transverse momentum is analysed
