Elastic and quasielastic scattering of 110-MeV polarized Na23 from Zr90

Angular distributions of the analyzing powers Tk0T (k=1,2,3), T20, and T21 for elastic and quasielastic scattering of 110-MeV polarized Na23 from Zr90 and the cross section for quasielastic scattering have been measured. Vanishing odd-rank tensor analyzing powers and the validity of the shape-effect relations indicate the importance of the projectile deformation for the interaction potential. The data are well explained by coupled-channel calculations using realistic double-folding potentials and taking into account projectile deformation and excitation.
