The exchange and self-interaction corrections are studied for the Thomas-Fermi model. Diamagnetic susceptibilities are calculated for various ions and the results are compared with SCF values and with experimental data. In addition, a Z-variation is introduced through an energy criterion. The analysis of numerical results shows an improvement when Z is varied.
