We employ a microscopic continuum-discretized coupled-channels reaction framework (MCDCC) to study the elastic angular distribution of the 7 Li= α + t nucleus colliding with 12 C and 28 Si targets at E Lab =350 MeV. In this framework, the 7 Li projectile is described in a microscopic cluster model and impinges on non-composite targets. The diagonal and coupling potentials are constructed from nucleon-target interactions and 7 Li microscopic wave functions. We obtain a fair description of the experimental data, in the whole angular range studied, when continuum channels are included. The inelastic and breakup angular distributions on the lightest target are also investigated. In addition, we compute 7 Li+ 12 C MCDCC elastic cross sections at energies much higher than the Coulomb barrier and we use them as reference calculations to test the validity of multichannel eikonal cross sections.

Effects of nonlocal potentials on(p,d)transfer reactions

et al. 2015

Background: Although local phenomenological optical potentials have been standardly used to interpret nuclear reactions, recent studies suggest the effects of non-locality should not be neglected. Purpose: In this work we investigate the effects of non-locality in (p, d) transfer reactions using non-local optical potentials. We compare results obtained with the dispersive optical model to those obtained using the Perey-Buck interaction. Method: We solved the scattering and bound-state equations for the non-local version of the dispersive optical model. Then, using the distorted wave Born approximation, we calculate the transfer cross section for (p, d) on 40 Ca at Ep=20, 35 and 50 MeV. Results: The inclusion of non-locality in the bound state has a larger effect than on the scattering states. The overall effect on the transfer cross section is very significant. We found an increase due to non-locality in the transfer cross section of ≈ 30 − 50% when using the Perey-Buck interaction and ≈ 15 − 50% when using the dispersive optical potential. Conclusions: Although the details of the non-local interaction can change the magnitude of the effects, our study shows that qualitatively the results obtained using the dispersive optical potential and the Perey-Buck interaction are consistent, in both cases the transfer cross sections are significantly increased.

The quadrupole collectivity of 28,30 Ne and 32,34,36 Mg, which are located around the conventional magic number of N = 20, was studied via proton inelastic scattering with a liquid hydrogen target by in-beam γ-ray spectroscopy in inverse kinematics. The deformation lengths were extracted from the angle-integrated cross sections for the first 2 + states using distorted-wave calculations. We have determined the deformation length of 36 Mg to be 1.90 +0.16 −0.17 fm for the first time. For 34 Mg and 30 Ne, the accuracies were improved. The evolution of quadrupole deformation in the vicinity of 32 Mg is discussed by comparing the present results with the theoretical calculations.
