“递推-矩阵法”求算光谱项的探讨

AN APPROACH TO DEDUCING SPECTROSCOPIC TERMS BY TAKING THE METHOD OF SUCCESSIVE DEDUCTION-MATRIX

本文提出了求算原子光谱项的一种新方法——“递推-矩阵法”。

This paper reports a new method—'the method of successive deduction—matrix' which can be used to calculate the atomic spectroscopic terms. The method works: (1) write a matrix B_1 by successive deduction of number; (2) make a matrix B_2 by arranging the direction of electron spin; (3) finally the matrix of deducing the atomic spectroscopic terms is finished by use of the calculating B_1×B_2. By use of Apple-Ⅱ microcomputer and with the program made in the paper, the atomic spectroscopic terms of P^N～l^N have been already deduced. It generally takes a few seconds to deduce all the spectroscopic terms for listed electronic configurations.
