摘　　要：运用含时多态展开方法研究微波场中里德堡锂原子高激发态的性质,得到锂原子在微波场中的跃迁几率,实现对量子态的操纵与控制.结果表明:选择合适的振幅、频率等参数,可以实现布居数在量子态之间的完全跃迁.Using the time-dependent multilevel approach （TDMA）, the properties of high excited Ryd- berg lithium atom have been obtained in the microwave field. The population transfer of lithium atom are studied on numerical calculation, quantum states are controlled and manipulated by microwave field. It shows that the population can be completely transferred to the target state by changing the chirped rate and field amplitude.
