摘要：

The topology of the non-adiabatic parameter space bundle is discussed for evolution of exact cyclic state vectors in Berry's original example of split angular momentum eigenstates. It turns out that the change in topology occurs at a critical frequency. The first Chem number that classifies these bundles is proportional to angular momentum. The non-adiabatic principal bundle over the parameter spare is not well defined at the critical frequency.
