Coupled-channel analysis of deuteron scattering on

The deuteron elastic and inelastic scattering on 56Fe is calculated by using the coupled-channel method and the collective motion models. Based on the experimental angular distributions of scattering processes, an optimal set of parameters are obtained for the deuteron's coupled-channel optical model potential and 56Fe's deformation including first ten low-lying excited states. The calculation results are in good agreement with the experimental data at low incident energies (Ed < 30 MeV), except for 41+(2.085 MeV) and 23+(2.960 MeV), and the deviation is found for several states at 56 MeV. That indicates further analyses and discussions are necessary
