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

I. A. Mazur, A. M. Shirokov, I. J. Shin +4

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…
