Abstract

It is shown in this paper that, using only common concepts of well known modern physics and quantum mechanics textbooks (as one- and two-electron atoms, perturbation theory), we can develop a simple and powerful method to calculate the binding energies of complex electron configurations, as well as ionization energies, X-ray levels, etc.

Keywords: Atomic structure; Z-expansion; relativistic corrections.

Resumen

En este artículo se muestra que usando solamente conceptos comunes bien conocidos que aparecen en los libros de física moderna y de mecánica cuántica (átomos con uno y dos electrones, teoría de perturbaciones), podemos desarrollar un método simple y poderoso para calcular las energías de ligadura de configuraciones electrónicas complejas, energías de ionización, niveles de rayos X, etc.

Palabras clave: Estructura atómica; desarrollo en Z; correcciones relativistas.
