Potentials of interaction of 10,11,12,13B isotopes with 12C

Abstract

A comparative analysis of calculations for the 12С(10В,10В)12С elastic scattering at Еlab(10B) = 41.3 MeV, the 12С(11В,11В)12С elastic scattering at Еlab(11B) = 40.0 MeV, transfer reactions 13С(11В,12С)12В and 14С(11В,12С)13В at Еlab(11B) = 45.0 МеВ was performed within the coupled-reaction-channels method (CRC) using previously deduced Woods-Saxon potentials for the interaction of 10,11,12,13В + 12С nuclei in the exit reaction channels, as well as potentials for these systems of nuclei generated by means of the double-folding method using theoretically modeled shapes for the distributions of protons and neutrons in 10,11,12,13В and 12С. The relationship of isotopic effects (differences of the calculated CRC cross sections when replacing the potential for a given pair of nuclei by interaction potential for one nucleus with the isotope of another nucleus) with the internal structure, e.g. the shapes of nucleon density distributions in the interacting nuclei, is investigated. The shapes (radial dependence) of recently deduced Woods-Saxon potentials and potentials calculated by means of the double-folding methods for the systems of 10,11,12,13В + 12С nuclei are compared. Based on the results of the analysis of experimental data, an assumption is made about the possible differences in the shapes of surface nucleon density distributions from the ones modeled theoretically in 10,11B isotopes.
