✦ Synopsis

Cross-section and analyzing-power measurements were performed for the 9Be(0, po)gBe and 9Be(0, p2)gBe * reactions. The depolarization parameter D was also measured on the first reaction.

The data were analyzed in terms of standard optical-model and macroscopic DWBA as well as coupled-channel calculations. The former approach does not reproduce well the elastic and inelastic analyzing-power data. Coupled-channel calculations provide a good description of both the crosssection and analyzing-power data. The D-data are interpreted in terms of contributions from both the quadrupole spin-flip mechanism and the nucleon-nucleus spin-spin interactions. E NUCLEAR REACTIONS 9Be (polarized p, p), (polarized p, p'), E = 220 MeV; measured ~r(0), analyzing power vs 0, depolarization vs 0 for elastic channel. Optical model, DWBA, coupled channels, spin-spin interaction models. Polarized beam.
