Disintegration of photoemulsion nuclei in small angle inelastic scattering of muons with 32 GeV momentum. Fast proton emission

Energy and angular distributions of fast protons, T>=30 MeV, estimated in the events of 32 GeV momentum muon inelastic scattering by photoemulsion nuclei at small values of inelasticity (< or approximately 0.1) and transfer four-momentum (Q2 approximately equal to 0.1 GeV2, x approximately 0.01) are analyzed. Comparison of characteristics of fast protons, emitted in muonic events and in the events of nucleus disintegrated by fast γ, π, p-particles, pionts to the difference at the level of approximately 2.5 errors, in angular dependence of proton energy spectrum inclination parameters and in its value for protons in forward hemisphere. The results obtained correspond completely to the data of experiments on pion total absorption by nuclei
