钾原子的低频调制激发
Slow frequency-modulated excitation of potassium atoms
【摘要】 对钾原子的低频调制激发进行了理论研究,用含时多态展开方法计算了处于微波场、静电场和低射频场中钾原子21s和19f两个Stark态的跃迁几率;通过改变低射频场的相位,我们得到了一些预期的结果;另外,我们还用特殊设计的低射频锯齿波代替低射频余弦波研究了方波振荡的变化,得到了许多有趣的结果,并给出了理论解释.
【Abstract】 Using the time-dependent multilevel approach(TDMA), we have calculated the square wave oscillation of the excited Rydberg potassium atoms in the presence of the microwave field, the static electric field and the radio-frequency(rf)field. Through changing the phase of the radio-frequency(rf)field and replacing the slow radio-frequency(rf) cosine sawtooth wave with the slow radio-frequency(rf) sawtooth wave, we have studied the change of the square wave oscillation and got some interesting results, and the theoretic explanation of these results are given.
