Abstract

Angular distributions of the differential cross section and the second-rank tensor analysing power T20 have been measured for the one-neutron transfer reaction induced by polarized 7Li ions on 208Pb at 33 MeV leading to five states in 209Pb. The experimental data were analysed simultaneously with data for elastic and inelastic scattering of 7Li by means of CCBA and CRC calculations. A strong effect of the transfer channels on the elastic scattering was found. Coupling to the transfer channels cancelled out the effect of projectile excitation on the elastic-scattering cross section but was unable to account fully for the renormalization factor of the double-folding potential found previously in an optical-model analysis of 7Li+208Pb elastic scattering. The second-rank tensor analysing power for the elastic scattering was strongly affected by the transfer channels.
