Asymptotic normalization coefficient for the study of the mirror nuclei 7Li and 7Be

Abstract

We present a theoretical study of the nuclear structure of the mirror nuclei 7Li and 7Be by using the asymptotic normalization coefficient (ANC) method through the transfer reactions 6Li(d,p)7Li and 6Li(3He,d)7Be. For these reactions, the elastic scattering and the transfer angular distributions were calculated considering cluster structures for the residual nucleus and the transfer particle. With the use of the Fresco code, we found the optical model parameters which reproduce the experimental data for the elastic and the transfer angular distributions and we got the ANC for the single particle model and the spectroscopic factor on the ground and the first excited states of each nuclei. This methodology allows to calculate the nuclear ANC which describes the peripheral behavior of both nuclei on their bound states.
