Coupled-channels effects for inelastic scattering of 15 MeV polarized deuterons from Ti and Sm isotopes

Cross sections and analyzing powers have been measured for elastic and inelastic scattering of 15 MeV deuterons from ¹⁴⁸'Sm and ¹⁵²Sm. These data, as well as previous data for the ${}^{\mathrm{48,\; 50}}\text{Ti}\text{(}\text{d}\text{, d'}\text{)}$ reaction have been analyzed in the coupled-channels approximation. Data for ⁴⁸Ti and ¹⁵²Sm are better described by the rotational model than by the vibrational model but the quality of the fits is not sufficiently good to establish ($\text{d}\text{, d'}$) reactions as a sensitive method of discriminating between these two models.
