Spectroscopic factor strengths using $abinitio$ approaches

Abstract

We have calculated the spectroscopic factor strengths for the one-proton and one-neutron pick-up reactions ${}^{27}$Al($d$,${}^3$He)${}^{26}$Mg and ${}^{27}$Al($d$,$t$)${}^{26}$Al within the framework of the shell model. We employed two different $abinitio$ approaches : an in-medium similarity renormalization targeted for a particular nucleus, and the coupled- cluster effective interaction. We also compared our results with recently determined experimental spectroscopic factors.
