Reaction calculations for 17O+12C including fusion within the molecular particle-core model.

Abstract

Scattering and fusion cross sections are calculated within the molecular particle-core model which describes the outermost bound neutron of $^{17}\mathrm{O}$ in a basis of eigenstates of the two-center shell model. The coupled-channel calculations in this paper include the channels of the elastic scattering of $^{17}\mathrm{O}$ on $^{12}\mathrm{C}$, the inelastic excitation of $^{17}\mathrm{O}$ to its first excited 1/${2}^{+}$ state, and the single-neutron transfer to the $^{16}\mathrm{O}$${+}^{13}$C system. The nuclear Landau-Zener effect generates structures in the calculated elastic, inelastic, and transfer cross sections which agree with the experimental data. Fusion calculations show enhancements due to the explicit treatment of inelastic excitation and transfer of the outermost bound neutron of $^{17}\mathrm{O}$.
