| Abstract: | In this paper the high-order adiabatic approximation (HOAA) method is formulated in a new form ko that the calculation is greatly simplified. using this improved HOAA method, we study the Berry phase effects of the Alkali atom in a slowly-changing strong magnetic field and also the non-adiabatic transitions between the instantaneous angular momentum states. The possible observability is also pointed out. |
