Abstract
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.

Summary
Deuteron-induced reaction catches much attention recently in association with applications for two main purposes. Many scientific facilities are served for these applications around the world such as ITER [1], IFMIF [2] and CiADS [3], and so on In these facilities, nuclear data including deuteron scattering angular distribution and neutron production cross section is essential for the design and operation activities. The input parameters of the theoretical models, like the optical model potential (OMP) and the collective motion model, are important to analyze the nuclear scattering processes and reactions. For incident energies up to 183 MeV and target nuclei ranging from 12C to 238U, An and Cai [5] obtained a set of global deuteron optical potential parameters which fitted well the experimental data. The coupled channel method was employed to calculate deuteron scattering angular distribution for 56Fe’s ground state and several low-lying excited states. The calculations were carried out by using ECIS code [7]
