摘要: 为描述高温高密度条件下氢分子间复杂的多体相互作用，以Ree和Bender对两个氢分子间平均作用势的CI计算结果为基础，提出一种可以描述旋转氢分子外域电子云分布的等效氦原子模型。采用该模型所计算的氢分子三体势与CI计算结果符合较好。还对氢分子间四体势进行了计算。

Abstract: To describe the complicate three-body and four-body interactions between hydrogen molecules at high temperatures and densities, an effective helium-atom model is presented to approximate electron cloud distribution of rotating hydrogen molecule at the outer space, on the basis of the average pair potential of Ree and Bender. The calculation results for three-body potentials are in good agreement with the CI calculations of Ree and Bender. The four-body ones are also given in this article.
