Abstract:
A Thomas-Fermi statistical analysis of Bader's interatomic surface developed in a previous work ( Delle Site L., Phys. Lett. A, 286 ( 2001) 61) is here extended by considering exchange effects and electron density's inhomogeneity at a basic level via the Thomas-Fermi-Dirac-Weizsacker model. The results obtained show interesting connections with Bohmian mechanics and lead to a statistical interpretation of the chemical properties of condensed systems at atomistic level.
