Abstract
We have performed proton inclusive scattering measurements at 500 MeV on , Ni, and Ta at angles at 65°, 90°, 120°, and 160°. Analyzing powers were also obtained for and Ni. The data extend in energy to the elastic scattering peak for at 90°. The cross-section data are described well by a direct knockout model and by quasi-two-body scaling calculations. Fits to analyzing power results by these theories are poor, and furthermore, we find a qualitative difference between the and Ni results. The Ni data show large positive analyzing powers at high detected particle energies, in keeping with results obtained on various targets from to at 800 MeV bombarding energy; the analyzing powers are predominantly negative or close to zero.
