Measurements of angular distributions for⁷Li elastically scattered from⁵⁸Ni at energies around the Coulomb barrier

Abstract

Abstract.Recently, experimental measurements of elastic scattering angular distributions for the system 7 Li+ 58 Ni at ten different energies around the Coulomb barrier were made by the Heavy-Ion Group. The measurements were made at the Tandem Van de Graaff Particle Accelerator Laboratory in the National Institute for Nuclear Research (ININ) in Mexico. In this work, preliminary elastic scattering angular distributions for five energies (E lab = 12.0, 12.5, 13.0, 13.5 and 14.22 MeV) are presented. The preliminary experimental data were analyzed using the São Paulo Optical Model Potential (SPP) which is based on a double-folding potential, reproducing very well these data. A comparison is made with old data reported back in 1973 and in 2012. Further analysis is in progress in order to fully understand this particular system, specially because 7 Li is known to be a weakly bound nucleus.

Evidence of the effect of strong stripping channels on the dynamics of the Li8+Ni58 reaction

“…For the 7 Li+ 58 Ni potential, the global parametrization of Cook [45] was initially considered, but the depths of the real and imaginary parts were further adjusted in order to best fit existing elastic scattering data for this system from Refs. [46][47][48][49] and constrained using dispersion relations, according to the analytic prescription of Ref. [50].…”

Elastic scattering of 7Li+58Ni: a phenomenological and microscopic analysis

“…There are many experimental [1][2][3][4][5][6] and theoretical [7][8][9][10][11][12][13] studies for 7 Li + 58 Ni nuclear system. In Ref.…”

“…In Ref. [1], the 7 Li + 58 Ni elastic scattering ADs at five different energies (12.0, 12.5, 13.0, 13.5 and 14.22 MeV) around the Coulomb barrier were experimentally measured. The measured data were analyzed using the double-folding (DF) Sao Paulo potential (SPP) for the real part as well as an imagi-nary Woods-Saxon (WS) potential.…”
