Reparametrising the Skyrme Model using the Lithium-6 Nucleus
Abstract
The minimal energy B=6 solution of the Skyrme model is a static soliton with symmetry. The symmetries of the solution imply that the quantum numbers of the ground state are the same as those of the Lithium-6 nucleus. This identification is considered further by obtaining expressions for the mean charge radius and quadrupole moment, dependent only on the Skyrme model parameters (a dimensionless constant) and (the pion decay constant). The optimal values of these parameters have often been deliberated upon, and we propose, for , changing them from those which are most commonly accepted. We obtain specific values for these parameters for B=6, by matching with properties of the Lithium-6 nucleus. We find further support for the new values by reconsidering the -particle and deuteron as quantized B=4 and B=2 Skyrmions.
