Analysis of proton + 12C scattering by microscopic coupled-channels calculations

NUCLEAR REACTIONS 12C(p, p), (p, p'), E=29.95, 35.2, 39.95, 65 MeV; calculated elastic and inelastic σ(E, θ) by microscopic coupled-channel (MCC) method with nuclear interaction from 3α resonating group method (3α RGM), and an effective nucleon-nucleon interaction of the density-dependent Michigan three-range Yukawa (DDM3Y). Comparison with experimental data, and with distorted wave Born approximation (DWBA). Discussed effect of the spin-orbit interaction.
