Abstract

α elastic and inelastic scattering on C12 is investigated with the coupled-channels calculation by using microscopic α-C12 potentials, which are derived by folding the Melbourne g-matrix NN interaction with the densities of α and C12. The matter and transition densities of C12 are obtained by a microscopic structure model of the antisymmetrized molecular dynamics combined with and without the 3α generator coordinate method. The calculation reproduces satisfactorily well the observed elastic and inelastic cross sections at incident energies of Eα=130, 172.5, 240, and 386 MeV without phenomenological fitting parameters adjusted to hadron scattering reactions. Isoscalar monopole and dipole excitations to the 02+, 03+, and 11- states in the α scattering are discussed.
