Abstract

The polarization of 3He particles scattered from 9Be, 12C and 16O has been measured at 18 MeV (and 20 MeV for 12C) over an angular range θc.m. = 20°–60°. Cross-section angular distributions out to 170° have also been obtained. The polarization distributions for the three nuclei appear similar and compare reasonably well with optical-model calculations. A spinorbit well epth greater than 3 MeV is required in the calculations to predict polarizations having the magnitudes of the measured values. Comparisons are made between the data and predictions which use optical-model parameter families related by the discrete and continuous ambiguities.
