The aim of this note is to ascertain the importance of the Fermi--Amaldi (FA) correction for the Thomas--Fermi (TF) theory of atoms. For this purpose, an analytic trial electron density has been chosen and the Thomas--Fermi--Amaldi (TFA) energy expression has been minimized by the Ritz method for the closed-shell atoms Ne, Ar, Kr, Xe, and Rn. The variationally obtained electron densities have then been used for calculating the diamagnetic susceptibilities of these atoms. The calculated values show only a very small improvement over values calculated by Jensen by an analogous procedure from the TF energy expression.
