Abstract
The differential cross section of the elastic scattering 3He( 4He, 4He) 3He has been measured at center of mass energies E c.m. between 28 and 44 MeV and in the c.m. angular range of 20° to 160°. The 3He polarization P at E c.m. = 42 MeV and θ c.m. = 132° was determined in a double scattering experiment. The analysis of the cross section data with the optical and the cluster model has been described previously. The phase shifts obtained in the cluster model calculations were used as starting values in a phase shift analysis. The resulting final real phase shifts and elasticity parameters give good fits to the cross section data. At 44 MeV the elasticity parameters show a pronounced odd-even dependence on angular momentum which had been found already in the case of the real phase shifts. The result of the polarization experiment | P| < 0.22 is consistent with cluster model predictions.
