Resumo

In this work we present an elastic scattering angular distribution for the Li-8+Ni-58 system measured at E-lab = 26.1 MeV. The Li-8 beam was produced in the Radioactive Ion Beams in Brasil (RIBRAS) facility using the Li-7 primary beam delivered by the 8-UD Pelletron accelerator. The angular distribution covers the angular range from 20 to 85 degrees in the center of mass frame. The data have been analysed by optical model and coupled channels calculations, including couplings to low-lying states in Li-8 and the spin-orbit interaction. Our results indicate that the inclusion of the spin-orbit interaction in the calculations is important to describe the data at backward angles. (AU)
