Resonances in Exotic ${}^7$He Nucleus within the No-Core Shell Model

Abstract

We present results of calculations of $n-{}^6\mathrm{He}$ elastic scattering phase shifts and resonances in ${}^7\mathrm{He}$. The calculations utilize the SS-HORSE method combined with ab initio no-core shell model calculations of the ${}^7\mathrm{He}$ and ${}^6\mathrm{He}$ nuclei with Daejeon16 and the JISP16 $NN$ interactions.
