PB-208(LI-7,LI-6)PB-209 REACTION AT 33 MEV AND ITS EFFECT ON ELASTIC-SCATTERING

Angular distributions of the differential cross section and the second -rank tensor analysing power T2O have been measured for the one-neutro n transfer reaction induced by polarized Li-7 ions on Pb-208 at 33 MeV leading to five states in Pb-209. The experimental data were analysed simultaneously with data for elastic and inelastic scattering of Li-7 by means of CCBA and CRC calculations. A strong effect of the transfe r channels on the elastic scattering was found. Coupling to the transf er channels cancelled out the effect of projectile excitation on the e lastic-scattering cross section but was unable to account fully for th e renormalization factor of the double-folding potential found previou sly in an optical-model analysis of Li-7+Pb-208 elastic scattering. Th e second-rank tensor analysing power for the elastic scattering was st rongly affected by the transfer channels.
