Energy dependence of optical potential in the near barrier elastic scattering of¹¹B from²³²Th

Abstract

Abstract. The elastic scattering cross sections of 11 B projectile on the 232 Th target have been measured at different bombarding energies close to the Coulomb barrier. The data has been analyzed for this system using the optical model ECIS code with phenomenological Woods-Saxon forms of the optical potentials. The energy dependence of the volume type real and imaginary parts of the optical potentials are derived from the best fit of the experimental angular distribution data. The total reaction cross sections are obtained from optical model analysis.

“…To overcome this problem, one has to determine the radial region of sensitivity, where the nuclear potential can be well and uniquely determined. In order to determine the so called sensitive radius, the Crossing Point [77,103,[107][108][109] and the Notch Perturbation [77,[110][111][112] methods are introduced. Below, are presented briefly the main features of each method.…”
