N2 - We investigate proton-production double-differential cross sections (DDXs) for 300- and 392-MeV proton-induced reactions on O, V, Tb, Ta, Au, Pb, and Bi. Emitted proton energies are measured with stacked scintillator spectrometers by the ΔE-E technique. Experimental results are compared with the intranuclear cascade (INC) and quantum molecular dynamics models. Although both models can reproduce spectral DDXs, there is a difference at the most forward and backward angles. The cause of these differences is discussed in terms of the refraction caused by the nuclear potential. Angular distributions of the present data are well accounted for by the Kalbach systematics plus INC one-step calculations. The quasi-free-scattering contribution increases with decreasing target mass and increasing emission energy.
