摘　　要：基于多体展式方法所导出的ＡｒＨＦ（Ｘ１Σ＋）的分析势能函数，用准经典的Ｍｏｎｔｅ－Ｃａｒｌｏ轨迹法研究了Ａｒ＋ＨＦ（ν′，Ｊ′）→Ａｒ＋ＨＦ（ν″，Ｊ″）振转非弹性碰撞过程。结果指出：Ａｒ对ＨＦ的振动能级的粒子分布影响不大，但对ＨＦ转动能级有弛豫作用。The non reaction dynamics of  Ar+HF (ν′,J′)→ Ar+HF (ν″,J″) has been studied based on the analytical potential energy function of  ArHF (X 1Σ +) using the quasiclassical Monte Carlo trajectory. It is reasonably found that the populations of rotational levels, particularly, for higher J values, are remarkably relaxed, however, it is not effective for the vibrational levels of HF.
