Angular dependence of the yield and spectrum shapes of protons produced in pA interactions at 7.5 GeV/c

Spectra of protons produced in the P+A→p+X reactions at 7.5 GeV/c initial pulse for C, Cu, Pb and U nuclei are measured. The measurements have been performed in the 10 deg-177 deg angle range for kinetic energies of secondary protons from 60 to 240 MeV. Angular dependences of the yield and spectrum, shapes of protons for different nuclei and initial energies are compared. The attempt to divide deep inelastic and quasifree reactions contributions has been made
