Ne对HF泛频激光振转能级粒子数分布的探讨

THE EFFECT OF Ne ON VIBRATION ROTATIONAL POPULATIONS OF HF OVERTONE LASER

基于多体展式方法所导出的ＮｅＨＦ（Ｘ１Σ＋）的分析势能函数，用准经典的ＭｏｎｔｅＣａｒｌｏ轨迹法研究了Ｎｅ＋ＨＦ（ｖ′，Ｊ′）→Ｎｅ＋ＨＦ（ｖ″，Ｊ″）振转非弹性碰撞过程．结果表明：Ｎｅ对ＨＦ的振动能级的粒子分布影响较大，在较低相对平动能下，对ＨＦ转动能级有驰豫作用．

The non elastic dynamics of Ne+HF(v′,J′)→ Ne+HF (v″,J″) has been studied based on the analytical potential energy function of NeHF(X 1Σ +) using the quasiclassical Monte Carlo trajectory. It is found that Ne has a greater effect on the vibrational level populations of HF,and it also has a relaxation effect on rotational levels of HF when the relative translation energy is lower.
