High-Energy Approach for Heavy-Ion Scattering with Excitations of Nuclear Collective States

Abstract

A phenomenological optical potential is generalized to include the Coulomb and nuclear interactions caused by the dynamical deformation of its surface. In the high-energy approach analytical expressions for elastic and inelastic scattering amplitudes are obtained where all the orders in the deformation parameters are included. The multistep effect of the 2${}^{+}$ rotational state excitation on elastic scattering is analyzed. Calculations of inelastic cross sections for the ${}^{17}$O ions scattered on different nuclei at about hundred Mev/nucleon are compared with experimental data, and important role of the Coulomb excitation is established.
