Ionization dominates if the particle has an energy larger compared to atomic binding energies . 若入射粒子能量大于原子的束縛能則電離是主要的。
Finally , the atomic coherent population trapping is studied in a multilevel laser - induced continuum structure system including cascade two - photon processes by means of quasi - classical theory . the condition leading to the atomic coherent population trapping and the dark state are given explicitly . the effects of atomic initial state and the laser intensity on the populations distributed in the atomic bound states are discussed 我們還運用準經典理論研究了含級聯雙光子過程的多束縛態激光場誘導原子連續態結構系統中原子布居數的相干俘獲,給出了產生相干俘獲的條件及暗態的表達式,討論了原子初態和激光強度對原于布居數的影響,揭示了原子相干對穩定rydberg原子的重要作用。
