A systematic study of inclusive pion scattering from targets of ${}_{}{}^4{}_{}{}^{}\mathrm{He}$, ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$, ${}_{}{}^{58}{}_{}{}^{}\mathrm{Ni}$, and ${}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$ has been performed at incident ${\pi }^{+}$ kinetic energies of $T_{{\pi }^{+}}=100, 160, 220, \mathrm{and} 300$ MeV. Particular attention was paid to the kinematic region where energy losses were greater than typical single-particle binding energies. The spectra of scattered pions were integrated to yield angular distributions and total inelastic-scattering cross sections. The spectra for all targets are similar, showing a peak near that expected for a single-step quasifree scattering process.
