Ab initio Hartree-Fock self-consistent-field (SCF) technique and the atomic cluster method have been applied to study the effective inter-atomic pair potential in liquid helium. The atomic cluster (He)9 with BCC geometry (only taking the first neighbors into account) is used to stimulate the average atomic configuration in liquid states. A theoretical effective potential is derived based on the new average coordination model and many-body series expansion approach. The obtained pair potential is very close to the experimental calibrated Exp-6 potential, by which both the isotherm and Hugoniot of liquid helium are well described.

提出了一种具有体心立方排列的原子团簇He9模型,用于模拟液氦中邻近原子的近程平均分布特征,并运用量子从头计算方法和原子团簇理论计算技术,首次从理论上计算了液态氦原子间等效作用对势。计算给出的等效对势能较好地再现液氦的等温压缩线及冲击压缩线,所提出的液体等效结构的原子团簇模型能比较合理地描述液氦近程结构特征以及原子间多体相互作用规律。还将理论对势函数与经验Exp-6势进行了比较。

提出了一种具有体心立方排列的原子团簇He9模型,用于模拟液氦中邻近原子的近程平均分布特征,并运用量子从头计算方法和原子团簇理论计算技术,首次从理论上计算了液态氦原子间等效作用对势。计算给出的等效对势能较好地再现液氦的等温压缩线及冲击压缩线,所提出的液体等效结构的原子团簇模型能比较合理地描述液氦近程结构特征以及原子间多体相互作用规律。还将理论对势函数与经验Exp-6势进行了比较。

Ab initio Hartree-Fock self-consistent-field (SCF) technique and the atomic cluster method have been applied to study the effective inter-atomic pair potential in liquid helium. The atomic cluster (He)9 with BCC geometry (only taking the first neighbors into account) is used to stimulate the average atomic configuration in liquid states. A theoretical effective potential is derived based on the new average coordination model and many-body series expansion approach. The obtained pair potential is very close to the experimental calibrated Exp-6 potential, by which both the isotherm and Hugoniot of liquid helium are well described.
