Abstract

Elastic scattering of a radioactive neutron-rich boron isotope, B-12, has been measured for the first time. Angular distributions for the elastic scattering of B-12 + Ni-58 have been measured at E-Lab = 30.0 and 33.0 MeV, which are just above the Coulomb barrier (V-B = 24 MeV). The obtained angular distributions were analyzed in terms of the large-scale coupled channel (CC) and coupled reaction channel (CRC) calculations, where several inelastic transitions for the target, as well as the most relevant transfer reactions, have been included in the coupling matrix elements. The roles of the spin reorientation and spin-orbit interaction in the reaction mechanism were also investigated. The one-neutron transfer reaction through a coupled reaction calculation had some effect on the elastic scattering of the system studied. (AU)
