Possibility to study a two-proton halo in ${}^{17}$Ne

Abstract

The nuclide ${}^{17}$Ne is studied theoretically in a three-body ${}^{15}$O+$p$+$p$ model. We demonstrate that the experimental condition for existence of a proton halo in ${}^{17}$Ne can be reasonably quantified in terms of $s/d$ configuration mixing. We discuss experimental evidences for a proton halo in ${}^{17}$Ne. We define which kind of experimental data could elucidate this issue.
