Fund Project:  Project supported by the National Natural Science Foundation of China (Grant No. 10774039), the Natural Science Foundation of Education Bureau of Henan Province, China (Grant Nos. 2010A140006, 2011A140009) , and the Research Planning Project of Basic and Advanced Technology of Henan Province, China (Grant No. 112300410025).

Abstract: The time-dependent multilevel approach (TDMA) and the B-spline expansion technique are used to study the properties of Rydberg lithium atom. The energy level structures of high excited states n = 7075, l = 05 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.
