摘要: 本文根据有界原子模型,通过对Dirac方程的求解,计算了H、Fe在不同物质密度、不同边界条件下的原子结构。结果发现:当物质密度较小时,近似于自由原子时的情况;当物质密度较大时,原子的外壳层电子能级有较大的变化。并且根据H在不同物质密度、不同边界条件下的原子结构的分析,展现了H的能带图象。

Abstract: In this paper a model of compressed atom for condensed matter is described. The atom is supposed to be enclosed in a sphere of radius R0, which is determined by the matter density. The orbital energies and the wave functions are obtained from the solutions of the Dirac equation in a self-consistent field with different boundary conditions. We find when the matter densities are small, the energy levels are just like the situation of free atom, when the matter densities are large, The energy levels are changed greatly. As an example the calculated results of compressed Iron are presented.
