Proton-induced nonelastic cross sections for $^{12}\mathrm{C}, ^{27}\mathrm{Al}, ^{56}\mathrm{Fe}$, and $^{208}\mathrm{Pb}$ are investigated in a low-energy region below 100 MeV down to nearly 0 based on framework of an intranuclear cascade (INC) model. We point out that there is scaling among the calculations including Coulomb repulsion; two cases shown: One trajectories with different impact parameters, other incident-energy dependence sections. first time calculated by usual INC model follow discrepancy between experimental data indicates scale breaking that, explanation breaking, it essential include discrete level constraints addition repulsion
