Ab initio study of island of inversion in odd-$A$ nuclei: Structure of ${}^{31,33}$Mg

Subhrajit Sahoo, Praveen C. Srivastava

We study the $N=20$ island of inversion region in the odd-$A$ Ne and Mg isotopes from the fundamental nuclear forces based on chiral two- and three-nucleon potentials. The state-of…
