Exclusive measurements have been made of He(p, 2p), (p, pd), (p, pt), and (p, ph) at 100 MeV. The primary protons were measured at two angles, 45' and 60', in coincidence with secondary protons, deuterons, tritons, or helions covering a wide range of angles on the opposite side of the beam, from -15' to -90' in plane, and from 0' to 30' out of plane. The satisfactory agreement in shape between the measured energy-sharing distributions and results of distorted-wave impulse approxirnation calculations suggests that this formalism is adequate for modeling the quasifree knockout reactions induced by 100 MeV protons on He. It is found that (70+10)% of the inclusive continuum yields in He(p, p') is attributable to quasifree scattering, with -30% arising from multiple scattering. At low energies of the scattered proton, the knockout of nucleons constitutes, over 90%%uo of the quasifree component, whereas at high energies the knockout of deuterons, tritons, and helions dominates the yield. Consequently the cluster knockout contributions fill in the yield at higher energies in the inclusive spectra, and quasifree peaks are not discernible.
