An analysis of theA-dependence of the target-diffractive cross-section is presented. Data on thet-dependence of the cross section are fitted in the usual exponential form. The mean multiplicity of negative particles produced diffractively is found not to be sensitive to the nuclear mass. TheA-dependence of the emitted proton multiplicity and the angular distributions of the produced charged particles suggest re-scattering of the emitted particles on other nucleons of the nucleus. All these facts are compared with results obtained by Monte-Carlo simulation according to a two-component Dual Parton Model.

Coherent inelastic interactions of pi+ and K+ mesons on Al and Au nuclei at 250-GeV/c

Cross-sections are obtained for coherent interactions of π+ and K+-mesons with Al and Au nuclei at 250 GeV/c, leading to three, five and seven charged mesons. The total coherent cross-section is (4.3 ± 0.5)% of the inelastic cross-section for each of the four meson-nucleus interactions. In 85% of the coherent events, the charged meson production is accompanied by neutral mesons. Effective mass distributions are presented for coherently produced particles, including charged mesons and photons, carrying total measured energy of more than 85% of the initial energy. Charged particle and γ spectra are analysed. No charge asymmetry is observed within the coherently produced cluster.

Light ion collisions with carbon target at 4.2 GeV/c/N are studied. Pion multiplicity distributions, momentum and angular spectra are analysed. These data are described in terms of models assuming independent interactions of nucleons from the projectile nucleus with the target.

An Estimate of Secondary Intranuclear Processes Contribution to Production of Cumulative Protons in $\pi^-$ C Interactions at 5-{GeV}/$c$

The contribution of possible intranuclear secondary processes (interactions of secondary mesons with nucleons and few-nucleon systems, interactions of Δ-resonances with nucleons) to cumulative proton production in π − c interactions at 5 GeV/ c is studied. It has been found that the contribution of secondary processes makes nearly half of the inclusive cross section of cumulative proton production at momenta p p ⩽ 0.75 GeV/ c .
