我们考虑的十二面体B= 7 Skyrmion的量子化中最重要的振动模式的列入。与刚体量子化相反，这种形式主义允许自旋3 - 2状态位于自旋7 - 2状态之下，与实验数据一致。还有一个低位自旋1 2态和两个自旋5 2态。我们发现自旋为7 2的激发态的均方根电荷半径比其它态的小。这个预言是Skyrme模型的一个重要特征，与更传统的核模型相冲突。
We consider the inclusion of the most important vibrational modes in the quantisation of the dodecahedral B= 7 Skyrmion. In contrast to a rigid body quantisation, this formalism allows a spin 3 2 state to lie below the spin 7 2 state, in agreement with experimental data. There is also a low lying spin 1 2 state and two spin 5 2 states. We find that the excited spin 7 2 state has a smaller root mean square charge radius than the other states. This prediction is an important signature of the Skyrme model, in conflict with more conventional nuclear models.
