摘要: 用以密度泛函理论为基础的离散变分方法研究了氦原子、氩原子、钠原子和钾原子,分别得到了氦原子、氩原子、钠原子和钾原子动量空间的轨道电子云密度分布,并与实验值做了比较.

关键词: 密度泛函理论, 离散变分方法

Abstract: Helium, Argon, Sodium and Kalium atoms are studied by using discrete variation method based on density functional theory. The orbital densities of He, Ar, Na and K atoms in momentum space have been calculated and the calculation results are as well compared with the experimental data.

Key words: density functional theory, discrete variation method
