Resumo

The elastic scattering of the radioactive proton-rich carbon isotope C-10 has been investigated. A full differential angular distribution for the elastic scattering of C-10 on a Ni-58 target has been measured at E-Lab = 35.3 MeV, which is just above the Coulomb barrier for this system (V-B = 27 MeV). The obtained angular distribution was analyzed in terms of coupled-channels, coupled-reaction-channels, and continuum-discretized coupled-channels calculations. In the coupled-channels calculation, several inelastic transitions of the target and the first (2(+)) excited state of the C-10 projectile were considered. The coupling to the first (2(+)) excited state of C-10 was shown to be very important to describe the rising of the cross section at backward angles. We also performed an analysis with the continuum-discretized coupled channels, considering the B-9 + p and Be-6 + alpha channels, which indicated a strong cluster configuration for the C-10 projectile.
