  The total and topological 4Hep cross sections as well as the cross sections
of the separate 4Hep interaction channels and the differential cross sections
of the elastic 4Hep scattering were measured using the 2m hydrogen bubble
chamber exposed to a separated beam of alpha-particles from the ITEP
synchrotron at 5 GeV/c (the kinetic energy of the initial protons in the
nuclear rest frame was 620 MeV). The data obtained have been compared with the
results of the previous experiments and with the theoretical predictions based
on the Glauber-Sitenko multiple-scattering theory.
