Strong coupling effect in the elastic scattering of the 10C + 58Ni system near barrier

NUCLEAR REACTIONS 58Ni(10C, 10C), (10C, 10C'), (10C, X)4He/7Li/7Be/10B/10C/12N, E=35.3 MeV, [secondary 10C beam from 3He(10B, 10C), E=54.0 MeV primary reaction at the Nuclear Science Laboratory of Notre Dame]; measured reaction products, particle identification spectrum, scattered 10C particles using three ΔE-E telescopes with silicon planar detectors, σ(θ); deduced differential σ; the results analyzed via coupled-channels, coupled-reaction-channels, and continuum-discretized coupled-channels (CDCC) calculations, with the consideration of 9B+p and 6Be+α channels as cluster configurations for the 10C projectile in CDCC approach. The 2+ inelastic transition in 10C in the projectile shown to be of crucial importance in describing the cross section data.
