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於布居數的影響，揭示了原子相干對穩定rydberg原子的重要作用。Effect of bound electron screening on neutrino capture
束縛電子屏蔽效應對中微子俘獲反應的影響The average abundance distributions of heavy elements in metal - poor stars can provide fairly direct and detailed information on the nucleosynthesis in every stage after the formation of galaxies. furthermore, it can put more accurate constraints on the chemical evolution of neutron - capture elements. the solution to this problem will have important effect on the solution to a series of problems about nuclear astrophysics and the galactic evolution
貧金屬星的中子俘獲元素豐度分佈能提供星系形成后各個階段核合成的較為直接和詳細的信息，並為星系化學演化的研究提供更為準確的約束，這一問題的解決將對核天體物理及星系化學演化的一系列問題的解決產生重要影響。The system has its own style. the trapping beams can be independently adjustable and three double - passed circularly polarized cooling / trapping beams intersect at the center of mot. about 1 107 cesium atoms with equivalent temperature of ~ 270 k are successfully trapped in our vcmot
在每束冷卻俘獲光的光強約4 . 9mw cm ~ 2 、失諧量為- 10mhz 、軸向磁場梯度約11 . 6gauss cm的條件下得到的冷原子樣品中典型的原子數約1 10 ~ 7個，溫度約270 k左右。Due to the different values of incident angle, there are two different propagation formats. one case is that the beam is finally trapped in a guide - like channel and propagates stably along the channel when the launching angle is smaller than a critical value. otherwise, it will propagate along the incident direction all along
由於入射角度的取值不同，格子孤子具有兩種不同的傳輸方式:當光束入射角小於某臨界角度時，光束可被類似波導形式的路徑俘獲，轉而沿該路徑向前傳輸;當光束入射角大於該臨界角時，孤子則不會被俘獲，而是沿著光束的入射方向直線傳輸。分享友人
