运用Ｍｏｎｔｅ－Ｃａｒｌｏ轨迹法研究了Ｋｒ（１Ｓｇ）＋ＨＦ（Ｘ１∑＋；ｖ＝１，２，３；Ｊ＝４）→Ｋｒ（１Ｓｇ）＋ＨＦ（ＸＩ∑＋，Ｖ’，Ｊ’）的碰撞过程，从而分析Ｋｒ原子对ＨＦ基频和泛频的影响。研究表明：在初始相对平动能Ｅｔ≤２５１.０ｋＪ／ｍｏｌ时，Ｋｒ原子能够减少产生基频的粒子数反转，增加产生泛频特别是Ｖ＝２能级的粒子数反转，并且，Ｋｒ原子有较强的弛豫高转动态（Ｊ’≥４）的能力，因此，Ｋｒ原子对ＨＦ泛频激光在提高光强和增强大气传输能力方面均有较大的改善。
The collisions of Kr (1Sg) + HF (X1Σ +; v = 1,2,3; J = 4) → Kr (1Sg) + HF (XIΣ +, V ’, J’) were studied by Monte- , To analyze the impact of Kr atoms on the fundamental frequency and the frequency of the HF. The results show that when the initial relative kinetic energy is Et≤251.0kJ / mol, the Kr atom can reduce the inversion of the number of particles generating the fundamental frequency and increase the inversion of the number of particles producing the uv band, especially the V = 2 level, and Kr Atom has a strong ability to relax and rotate at high (J’≥4). Therefore, Kr atoms have greatly improved the HF-frequency laser in improving the light intensity and enhancing the atmospheric transport ability.
