Abstract

The continuum cross sections and analyzing powers from the H2, 3,4He(p,p) and 3,4He(p,d) reactions were measured for 98.7 and 149.3 MeV polarized protons in the angular range 17.5° to 60°. The H2 and He3 data show strong quasifree contributions with more ambiguous results for He4. These data are compared with distorted-wave impulse approximation calculations based on quasifree nucleon and deuteron knockout. Overall, the agreement between theory and experiment is moderately good. However, some significant discrepancies are observed and corrections to the simple model are discussed.
