The excitation of theΔ resonance is observed in proton collisions on C, Nb and Pb targets at 0.8 and 1.6 GeV incident energies. The mass E0 and widthΓ of the resonance are determined from the invariant mass spectra of correlated (p, π±)-pairs in the final state of the collision: The mass E0 is smaller than that of the free resonance, however by comparing to intra-nuclear cascade calculations, this reduction is traced back to the effects of Fermi motion, NN scattering and pion reabsorption in nuclear matter.

Multiplicity of Secondary Particles in Inelastic Proton - Neon Interactions at 300-{GeV}/$c$

Azimov, S.A. ; Inogamov, Sh.V. ; Kosonovsky, E.A. ; et al.

The data on the total inelastic and partial cross sections in pNe interactions at 300 GeV are presented. It is found that the total cross section, σin(pNe)=356±13 mb, and multiplicity distributions of the number of negative and relativistic charged particles are in good agreement with predictions of a multiple-scattering model based on Glauber's approach. The multiplicity of negative particles obeys the Koba-Nielsen-Olesen (KNO) scaling, but it is observed that the KNO function depends on the atomic mass number of the target. From an analysis of the average multiplicities of secondary particles, it is shown that approximately 10 percent of the fast (p≳1.2 GeV) positive secondaries are protons, which are derived from the nucleons in the neon nucleus.
