摘要：运用含时多态展开方法和B-样条函数研究了微波场中里德伯锂原子高激发态的性质,得到锂原子量子态n=70—75,l=0—5的能量,并分析了里德伯锂原子高激发态n=70—75,l=0—5在微波场中的跃迁几率.结果表明:通过优化微波场参数可以实现量子系统从初始态到目标态的完全跃迁,且在跃迁过程中,每个l态都起至关重要的作用.
The time-dependent multilevel approach （TDMA） and the B-spline expansion technique are used to study the properties of Ry- dberg lithium atom. The energy level structures of high excited states n = 70-75, l = 0-5 and population transfer of lithium atom in a microwave field are studied by numerical calculation. The results show that the coherent control of the population transfer in microwave field from the initial to the target states can be accomplished by optimizing the microwave field parameters, and that each state plays a crucial role in the transition process.
