The ${}^{19}$N($n$,${\hat{I}}^3{)}^{20}$N capture rate in light of the probable bubble nature of ${}^{20}$N

Abstract

We aim to explore the bubble nature of the exotic nucleus ${}^{20}$N within the microscopic antisymmetrized molecular dynamics (AMD) approach. Constraining its structural parameters, we analyse its static properties. Subsequently, we use the AMD infused finite-range distorted-wave Born approximation theory to calculate the Coulomb breakup of ${}^{20}$N as an indirect approach to estimate the ${}^{19}$N$(n,{\hat{I}}^3{)}^{20}$N radiative capture rate.
