Low-energy structure and anti-bubble effect of dynamical correlations in<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:msup><mml:mrow /><mml:mn>46</mml:mn></mml:msup></mml:math>Ar
The low-energy structure of ${}^{46}$Ar is of particular interest due to the possible coexistence of different shapes and the possible existence of proton ``bubble'' structures. In this work, we apply a beyond relativistic mean-field approach to study the low-energy structure of ${}^{46}$Ar. Correlations beyond the mean field are introduced by …
