Analyzing power of proton-nucleus elastic scattering between 80 and 180 MeV

Elastic scattering of polarized protons of 80-180 MeV from a number of target nuclei ($24lAl208$) has been measured. The systematic energy and target mass dependence of the cross section and analyzing power angular distributions is discussed. The data have been analyzed within the framework of a conventional optical potential model, and the behavior of the potential parameters as a function of energy is investigated. Comparisons are made with results obtained at energies greater than 180 MeV and with predictions obtained from microscopic models.
