The position and width of avoided crossings of Li atom energy levels in a static electric field is presented by using the B-spline basis set method combined with the model potential.Using the time-dependent multilevel approach,the population of Li atoms is transferred to the target state completely by one-photon,two-photon or a single multiphoton adiabatic rapid passage,which requires only a small frequency sweep.The calculation results agree well with the experiment and novel explanations are given to understand the experimental results.
