Continuum spectra for the inclusive reaction {sup 90}Zr({ital p},{ital p}{prime}) have been measured for scattering angles between 24{degree} and 145{degree} at incident energies of 80 and 120 MeV. The spectra and angular distributions at various ejectile energies above 20 MeV are compared with published experimental data for {sup 90}Zr({ital p},{ital n}) at the same incident energies. Results of statistical multistep direct emission calculations are in excellent agreement with the experimental angular distributions. The extracted strength of the effective nucleon-nucleon interaction is shown to be reasonable with respect to absolute magnitude and energy dependence. A phenomenological parametrization of the angular distributions also describes the experimental quantities well.
