Investigation of the elastic and inelastic scattering of α-particles from 13C in the energy range 26.6–65MeV

Abstract

We have measured the differential cross-sections for the elastic and inelastic scattering of [Formula: see text]-particles on [Formula: see text]C target at the isochronous cyclotron U-150 M INP Republic of Kazakhstan. The beam energies of [Formula: see text]-particles were 29[Formula: see text]MeV and 50[Formula: see text]MeV. As a result of research we obtained new experimental data for the [Formula: see text] + [Formula: see text]C elastic scattering and inelastic one leading to the 3.68 ([Formula: see text]), 6.86 ([Formula: see text]) and 7.5 ([Formula: see text])[Formula: see text]MeV excited states of [Formula: see text]C nucleus. The experimental results on elastic scattering were analyzed within the framework of the optical model using Woods–Saxon potential and the double folding one. The theoretical calculations for the concerned excited states were performed using the coupled channel (CC) method. The optimal deformation parameters for the excited states of [Formula: see text]C nucleus were extracted.
