MICROSCOPIC COUPLED-CHANNEL STUDIES OF THE PROTON + 12C SCATTERING AT EP = 65 MEV

摘要

We have performed the microscopic coupled-channel (MCC) calculations for the p + 12C inelastic scattering at Ep = 65 MeV. The nuclear interactions for the proton -12C system are constructed from the folding model, which employs the internal wave function of 12C, obtained from the 3α resonating group method (3α RGM), and an effective nucleon-nucleon interaction of the density-dependent Michigan three-range Yukawa (DDM3Y). The MCC calculation with the 3αRGM + DDM3Y nicely reproduces all of the differential cross sections for the elastic and inelastic scattering, which are 3a excitations in 12C. The effect of the spin-orbit interaction, obtained in a simplified manner with the folding procedure, is discussed.
