Description

The experiments at the DC-60 heavy ion accelerator in nuclear physics are focused, on obtaining the missing information on the internuclear interaction potentials, with the contribution of the elastic transfer process in the region of the rear angles. In this work, we measured the angular distributions of elastic scattering of $^{10}$B($^{14}$N,$^{14}$N)$^{10}$B at energies E$_{lab}$ = 21 and 24.5 MeV in the range of angles 30$^0$-165$^0$ in the center of mass system. In the experiment, self-sustaining $^{10}$B films with a thickness of 30-40 μg/cm$^2$ were used as target [1]. The measurements were carried out using the ΔЕ-Е method of registration and identification of nuclear reaction products.

The analysis of angular distributions together with literature data [2, 3] was carried out in the framework of the optical model and folding model using the FRESCO program. The optimal values of potential parameters are found. It should also be noted that we introduced two additional potentials in a phenomenological way, exploring the sensitivity of scattering to the optical potential.
