Abstract: We study the isospin-dependent component of the effective nucleon-nucleon interaction which causes the \ensuremath{\Delta}T=1 (p,p') and (p,n) reactions off nuclei. It is shown that, at intermediate energies, the modification to the impulse approximation comes from the g-matrix-type correction and the rearrangement term. They are numerically estimated with the isospin-asymmetric nuclear-matter reaction matrix approach. The isobaric-analog transitions $^{42}\mathrm{Ca}$(p,n${)}^{42}$Sc and $^{48}\mathrm{Ca}$(p,n${)}^{48}$Sc are analyzed.
