Molecular particle-core model and its application toC13-C13scattering

On the basis of the two-center shell model a theory is developed for the excitation of loosely bound nucleons in heavy ion collisions. These nucleons move in the two-center shell model potential generated by all the nucleons and are described by molecular wave functions. The model is applied to calculate the cross sections for the elastic and inelastic ${}_{}{}^{13}{}_{}{}^{}\mathrm{C}$-${}_{}{}^{13}{}_{}{}^{}\mathrm{C}$ scattering. The cross sections show intermediate structures caused by the excitation of quasibound resonances in the molecular nucleus-nucleus potential.
