For the first time, a realistic microscopic calculation for low-energy neutron-nucleus elastic scattering off open-shell nuclei is carried out within the framework of particle-vibration coupling (PVC). In this study, the pairing correlations of the ground state are taken into account. The dependence of the angular distributions on the pairing gaps is discussed.

Deuteron elastic scattering off 12C is described in the framework of three-body Faddeev-type equations. Analyzing powers are calculated using the PEST16 potential, which is a separable rank-one representation of the Paris potential. Satisfactory agreement with the experimental data is found within the PEST16 potential.

In this brief report, we make a short review of progress in developing the microscopic optical potential in recent years. In particular, we present our current studies and plans on building the microscopic optical potential based on the so-called nuclear structure models at low energies.
