采用含时多态展开方法,结合B样条函数和单电子原子模型势研究微波场中钠原子里德伯高激发态的性质,得到钠原子的能级结构及在微波场中的布居数迁移,实现对量子态的操纵与控制.结果表明：含时多态展开方法结合B样条函数和单电子原子模型势是有效研究微波场中碱金属原子性质的一种方法;选择合适的啁啾率、振幅等参数,可以实现布居数在量子态之间的完全迁移和量子态囚禁.
英文摘要：
Using the time-dependent multilevel approach（TDMA） and combining the B-spline expansion technique and the model potenial method of atom,the properties of Rydberg sodium atom are investigated.The energy level structure of high excited states and population transfer of sodium atom in a microwave field are studied by numerical calculation,and quantum states are controlled and manipulated by microwave field.The results show that the method we used can be applied to the investigation of the properties of alkali-metal atoms in external field,that the population is very sensitive to the parameters of chirped rate and field amplitude,and that the population can be completely transferred into the target state and trapped there by changing the chirped rate and field amplitude.
