在高分辨率的非弹性电子散射中，观察到从基态到Ex = 10.319 MeV的状态的通常很强的磁偶极子跃迁，这与纯独立粒子壳模型的预期相反。然而，由于强基态相关性，跃迁强度可以用相干自旋翻转跃迁来解释。
An ususually strong magnetic dipole transition from the ground state to a state at Ex = 10.319 MeV in40Ca has been observed in high-resolution inelastic electron scattering, contrary to expectations from the pure independent particle shell model. The transition strength, however, can be accounted for by coherent spin-flip transitions due to strong ground-state correlations.
