Scientists reveal a new feature in nuclear physics: the existence of kaonic nuclei and hyper-nuclei. These findings can enhance our understanding of nature and contribute to technological progress.
Abstract
The properties of kaonic nuclei are studied using a two-dimensional Skyrme–Hartree–Fock model with a $KN$ Skyrme force. We focus in particular on the instability of the solutions for a too strong $KN$ interaction, which determines a maximum value of the kaon binding in this approach. We then analyze the change of the deformation properties of several core-deformed nuclei caused by the added kaon, and find a shrinking of the core and in some cases a complete loss of deformation.
