TL;DR: In this paper, a simple and convenient method is derived for evaluating linked Goldstone diagrams in an angular momentum coupled representation, which can be used to evaluate any effective interaction and/or effective operator diagrams for both closed-shell nuclei (vacuum to vacuum linked diagrams) and open-shell nested diagrams (valence linked diagrams).

TL;DR: In this paper, the inelastic and fusion excitation functions were analyzed using an interference mechanism between the barrier and internal waves of the heavy ion optical potential, and the undamped overlapping molecular resonances were found to be the main dynamical mechanism for the gross oscillations in the excitation function.
Abstract: The inelastic and fusion excitation functions are analyzed using an interference mechanism between the barrier and internal waves of the heavy ion optical potential. The undamped overlapping molecular resonances are found to be the main dynamical mechanism for the gross oscillations in the excitation function. Our result suggests a rather interesting correlation between the total reaction excitation and the direct surface reaction excitation function. Its origin may be understood as follows: At the resonance, the wave function is pulled into the nuclear interior, and thus, the total reaction cross section is at maximum. The direct surface reaction is, however, shifted by a small phase difference near the surface region. This picture should be valid in the case of overlapping molecular resonance of the heavy ion systems. Good agreement between calculated and experimental inelastic and fusion excitation functions for $^{12}\mathrm{C}$+ $^{12}\mathrm{C}$ and $^{16}\mathrm{O}$+ $^{16}\mathrm{O}$ is obtained.

TL;DR: In this paper, an energy independent optical potential for nucleon-nucleus scattering is derived and a simple relation between energy dependent and energy independent potentials is established showing that the latter has the same thresholds as the former.
Abstract: An energy independent optical potential for nucleon-nucleus scattering is formally derived. A simple relation between energy dependent and energy independent potentials is established showing that the latter has the same thresholds as the former. A generalized dispersion relation for energy independent potentials is found and compared to the conventional dispersion relation of the generalized energy dependent optical potentials.
