Elastic scattering analysis of 10,11B+40Ca at 50 MeV using Woods-Saxon and folding potentials

Abstract

An attempt has been made very recently to perform a scattering experiment on ${}^{10,11}\text{B}$+${}^{40}\text{Ca}$ systems at the energy of 50 MeV at General Purpose Scattering Chamber (GPSC) of Inter-University Accelerator Centre (IUAC), New Delhi, India. A comprehensive analysis of the elastic scattering data is carried out using different versions of optical potentials, such as the Woods-Saxon (WS) potential, the M3Y-Paris double-folding (DF) potential and the semi-microscopic Sao Paulo potential (SPP2). We have arrived at a new set of optical model (OM) parameters which are compared with the data obtained by Glover et al. (1980) at 46.6 MeV and 51.5 MeV. There is substantial change in the real and imaginary potential strengths when analyzed using WS potential. Both the systems exhibited absorption and showed structural differences between ${}^{10}\text{B}$ and ${}^{11}\text{B}$, with the former having a deeper real potential and a more confined interaction region. With a combination M3Y-Paris (real) and WS Volume (imaginary) potential, experimental cross-sections are reproduced which also reveals the extended structure of ${}^{11}\text{B}$. SPP2 potential provides significant information on reaction dynamics providing larger proton and neutron radii of ¹¹B as compared to ¹⁰B. Finally, We extracted a new set of consistent OM parameters that is applicable in understanding the reaction dynamics of light-heavy ion interactions.
