A method is proposed for determining the barrier transmission coefficient for the outgoing protons from the intranuclear cascade process in (p,p′x) reactions. In this method, the coefficient is defined as the ratio of the cross section of the proton-nucleus reaction to that of the neutron-nucleus reaction and is calculated by using empirical equations for the cross sections with no free parameters. The determined coefficient is incorporated into an intranuclear cascade model followed by an evaporation model, and the double-differential cross sections are calculated for (p,p′x) reactions around 50 MeV on heavy targets with A≥120. The present results agree well with experimental observations. Remarkably, the spectra for Bi209 and Au197 are accounted for even though the evaporation contributions are negligibly small.
