Inelastic scattering ofHe3from samarium isotopes at 53 MeV

Angular distributions of ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ inelastic scattering from the stable even isotopes of samarium were measured at an incident particle energy of 53.4 MeV. The data for $2^{+}$ and $3^{-}$ collective states extend to 150° for ${}_{}{}^{144,148,150}{}_{}{}^{}\mathrm{Sm}$ and to 100° for $2^{+}$ states in ${}_{}{}^{152,154}{}_{}{}^{}\mathrm{Sm}$. The cross sections span approximately seven orders of magnitude. The data were analyzed with the distorted-wave Born approximation and the strong-coupling approximation. Quadrupole and octopole deformation parameters thus obtained are compared with results from analyses of proton and $\alpha$-particle-scattering data.
