Abstract

The cross sections of helion scattering leading to the ground state and the first four to six excited states of the even-even stable samarium isotopes were measured at an incident enegy of 40.9 MeV. The results are analysed in terms of the strong coupling approximation assuming the 144, 148Sm 150Sm and 152, 154Sm nuclei to be harmonic vibrators, an asymmetric rotator and symmetric rotators respectively. A systematic study was carried out to deduce the 2γ(γ = 2, 3, 4, 6) pole deformation parameters and a single common optical-model potential for this nuclear range. A description of the elastic and inelastic scattering cross section is given in the framework of the coupled-channels theory and the collective model; the importance of multistep processes in inelastic scattering is emphasized.
