“…Optical potentials were determined by use of a folding model with the nuclear matter approach of JLM [5] 034606-2 that incorporates a complex energy-and density-dependent parametrization of the effective interaction obtained in the Brueckner Hartree-Fock approximation from the Reid hardcore nucleon-nucleon (NN) potential. In the JLM model the complex form factor for the optical potential is given by…”

“…Because the local-density approximation used in Eq. (1) does not represent properly the surface effects in finite nuclei, and to increase the flexibility of the folding potential, a smearing function has been introduced [5], such thatŨ…”

“…It should be noted that originally the JLM model was developed to describe nucleon-nucleus optical potentials, and its density dependence is calibrated for densities not exceeding the saturation value in nuclear matter [5].…”

“…Previous studies of scattering of p-shell nuclei showed that a doublefolding procedure with a modified version of the nuclear matter approach of Jeukenne, Lejeune, and Mahaux (JLM) [5] provided a good description of potentials for loosely bound nuclei by use of the normal absorptive component of the JLM nucleon-nucleon interaction. However, the real part of the potential required significant renormalization to account for effects of the DPP [4,6].…”

Precision data have been obtained for the elastic scattering of 17 F on 12 C and 14 N at 10 MeV/nucleon to clarify the reaction mechanism for loosely bound nuclei at low energies and to assess the validity of a double-folding procedure to predict optical model potentials for use in indirect methods for nuclear astrophysics. The double-folding procedure incorporates density and energy-dependent effective nucleon-nucleon interactions with realistic densities consistent with experimentally determined asymptotic normalization coefficients. The derived potentials provide an excellent description of the data and point to a complete dominance of absorption at the barrier. A semiclassical analysis in terms of multireflection barrier-internal barrier series expansion of the scattering amplitude shows that only the barrier component survives in the scattering process, pointing to the peripheral character of the reactions.

“…Folding model analysis using the complex, density and energy dependent NN interaction of Jeukenne, Lejeune and Mahaux (JLM) [13], as well as other G-matrix effective interactions, where corrections due to the strong DPP have been included, confirmed that the elastic distribution could be described using deep and extremely transparent potentials. The intermediate angle structures have been discussed using the semi-classical uniform approximation for the scattering function of Brink and Takigawa [14].…”

We present a complete analysis of elastic scattering 6 Li+ 16 O at 4 and 5 MeV/nucleon. Using either traditional Woods-Saxon or a range of semi-microscopic folding form-factors we find that the data require deep, highly transparent potentials. Physically relevant solutions are selected according to dispersion relation. The intermediate angle structures and the oscillatory increase of the cross section at large angles is interpreted either as a pre-rainbow oscillation resulting from the interference of the barrier and internal barrier far-side scattering subamplitudes, or, equally well, as a resonant diffraction arising from two Regge poles located in peripheral waves. Both semi-classical and Regge pole approaches allow a dynamical separation of the resonant component of the S-matrix.
