摘要

Using the B-spline basis set method combined with model potential,the Stark energy level of rubidium atoms in the vicinity of n =30 is presented.By using a using time-dependent multilevel approach,we calculate the population redistribution of high Rydberg rubidium atoms under the interaction of external time-dependent halfcycle pulses.Our numerical results show that the population of rubidium atoms can be driven to lower or higher n levels with a train of half cycle pulses,the final population distribution of all the l states for the same n is observed after these interactions.
