Self-Consistent Field for Iron

Abstract

This paper reports the results of self-consistent field calculations for the ${d}^{6}{s}^{2}$ configuration of iron. Preliminary calculations were made on the Massachusetts Institute of Technology differential analyzer. The final results were obtained by numerical integration. For all of the wave functions the discrepancy between final and semi-final values of $Z$ is less than 0.010. A brief discussion of the relation of the results to spectroscopy and to Slater's theory of ferromagnetism is given.
