Аннотация

The differential cross sections of elastic and inelastic (3/2– excited state of 13С, Ex = 3.684 MeV)
scattering of deuterons by 13С nuclei at energy Ed = 18 MeV in the angular range θlab = 10o-75o have been measured
at the U-150M cyclotron (Almaty, Kazakhstan). The total error of the experimental data obtained does not exceed
10%. The standard dE-E method of registration and identification of interaction products was used in the
experiment. Thin carbon films with a thickness of about 150 μg/cm2 of about 80% enrichment by 13C were used as
targets. A theoretical analysis was made within the framework of the optical model of the nucleus and the coupled
channels method. The values of the quadrupole deformation were determined, which are in good agreement with the
literature data. It is shown that in order to improve the theoretical description of experimental data, additional
mechanisms (reactions, other inelastic processes) that can influence the formation of scattering cross sections must
be taken into account in the calculations.
