Investigation of deuteron interaction with 13С nuclei

Abstract

The differential cross sections of inelastic deuteron scattering on the ¹³C nuclei were measured at energies 14.5 and 18 MeV for the following excited states: 3.09 MeV (1/2⁺), 3.68 MeV (3/2^-) and 6.86 MeV (5/2⁺). Experimental data were obtained with high angular resolution in a wide range of angles from 10° to 110° in the center of mass system, which made it possible to study in detail the structure of angular distributions. The angular distributions of elastic scattering of deuterons on ¹³C nuclei were analyzed. A comparison of the description of elastic scattering between the optical model of the nucleus and the double folding model was performed. The double folding method proved to be best only for large transmitted momentums. A systematics of the optical potential (OP) parameters for the ¹³C(d,d)¹³C in the energy range Ed=13÷18 MeV was obtained by minimizing χ². The obtained parameters were used within the framework of the coupled channel method (CC) to analyze the angular distributions of elastic and inelastic scattering of deuterons on ¹³C nuclei. Due to analysis of inelastic deuteron scattering, the deformation parameters of low-lying excited states of the ¹³C nucleus were calculated, consistent with literature data.
