ResumoThe fully quantum-mechanical statistical multistep direct emission theory of Feshbach, Kerman, and Koonin is used to analyze the differential cross sections of ($p,n$) reactions on $^{48}\mathrm{Ca}$, $^{90}\mathrm{Zr}$, $^{120}\mathrm{Sn}$, and $^{208}\mathrm{Pb}$ from 25 to 45 MeV. The interacting particles are described by distorted waves and the interactions inside the nucleus are described by a single-particle model. The absolute magnitudes, as well as the angular variations of the continuum spectra, are well reproduced and the relative contributions of single and multistep processes are evaluated.[NUCLEAR REACTIONS $^{48}\mathrm{Ca}$, $^{90}\mathrm{Zr}$, $^{120}\mathrm{Sn}$, $^{208}\mathrm{Pb}$ ($p,n$). Calculated cross sections and angular distributions. Deduced two-body interaction strength.]
