| Abstract: | The Airy structure of the nuclear rainbow and prerainbow in inelastic and elastic α + 16O scattering is studied with the coupled channel method using a folding potential derived from the microscopic wave functions of 16O. The theoretical calculations reproduce the characteristic energy evolution of the Airy minimum of the experimental angular distributions. The energy levels with α-cluster structure in 20Ne are reproduced well using the potentials determined from the analysis of scattering. It is shown that the emergence of the K = 0+ 3 α-cluster band with core excitation at 7.19 MeV in 20Ne is intimately related to the emergence of the prerainbow and rainbow in inelastic scattering to the 16O(0+ 2). It is found that the α-cluster states with core excitation, the prerainbow and the rainbow in inelastic scattering are understood in a unified way as well as in the case of elastic scattering. |
