In this paper , we prove that for a three - level atom in a circularly polarized electromagnetic wave , there is a coherent superposed state of its two states such that when the atom is initially in the state , under the zero - order approximation , the atom is always in the state hereafter , while the occupation probabilities that the atom is in other states are zero ; under the first - order approximation , the atom is nearly in the state , while the occupation probabilities that the atom is in other states near zero
本文證明：對圓極化光中的三能級原子，存在著由它其中的兩個態(tài)構(gòu)造的一個特殊的相干疊加態(tài)，當(dāng)原子最初處于這個態(tài)時，它以后將總是幾乎處于這個態(tài)，而原子處于其他態(tài)的概率接近于零。
