Abstract
Elastic scattering of He-4+Ca-40 and He-4+Ti-44 reactions at backward angles has been analyzed using two differentmodels, microscopic and semimicroscopic folding potentials. The derived real potentials supplemented with phenomenological Woods-Saxon imaginary potentials, provide good agreement with the experimental data at energy E (c.m.) = 21.8 MeV without need to renormalize the potentials. Coupledchannels calculations are used to extract the inelastic scattering cross section to the low-lying state 2+ (1.083 MeV) of Ti-44. The deformation length is obtained and compared with the electromagnetic measurement values as well as those obtained from previous studies.
