一、引言量子力学对氢原子处理得到满意的结果,不仅得到的能阶符合实验结果,并且所得的轨函亦可用来对周期表各元素作一大致的描述。对于多电子原子模型,量子化学尚无严恪的数学处理方法,虽然在应用近似处理方法上不断有所改进,使结果更加逼近,但由于元素及化合物的许多性质只决定于最外层电子(或次外层电子),它们微少的电离势差别及轨函改变就可导致性质的大幅度变化。用目前的多电子原子模型的近似处理法,还无
I. INTRODUCTION Quantum mechanics gives satisfactory results for the treatment of hydrogen atoms. Not only the energy level obtained accords with the experimental results, but also the derived orbit functions can be used to describe the elements of the periodic table in a general way. For the multi-electron atomic model, there is no mathematical treatment of quantum chemistry. Although there are some improvements in the application of approximate methods to make the results more approximate, many of the properties of the elements and compounds are determined only by the outermost electrons Or sub-outer electrons), their slight differences in ionization potential and changes in the orbit can lead to substantial changes in the nature. With the current multi-electron atomic model of the approximate approach, nothing else
