Prediction of electron affinities from fundamental theorems involving the electron density, , and the z -1 perturbation expansión

The electrón affinities of the elementa H through F have been obtained wlthin the frameworlt of fundamental theorems Involving the electrón denslty, , and the Z-1 perturt and gt;ation expansión. The agreement between the predicted and observed valúes of electrón affinities is very satisfactory.
