Comparison of Inelastic Scattering fromSm152with Coulomb Excitation Theory

In order to check the theory of electric quadrupole Coulomb excitation, accurate measurements have been made of differential cross sections for inelastic scattering from the first excited state of ${\mathrm{Sm}}^{152}$. Protons, deuterons, and alpha particles of energies in the region of 4 Mev were used as the bombarding particles. In addition to the angular distribution of inelastically scattered deuterons, measurements were also made with protons at two scattering angles and at a backward angle with deuterons and alpha particles of different incident energies. The data are found to be in excellent agreement with the semiclassical description of the Coulomb excitation process.
