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