摘　　要：Using the time-dependent multilevel approach and the B-spline technique,populations of Rydberg lithium atoms in chirped microwave pulses are demonstrated.Firstly the populations of two energy levels are controlled by the microwave pulse parameters.Secondly the atoms experience the consequence 70s-71p-72s-73p-74s in a microwave field using optimized microwave field parameters.It is shown that the coherent control of the population transfer in the microwave field from the initial to the target states can be accomplished by optimizing the microwave field parameters.
