Abstract:
We studied an opportunity to develop a full-potential orbital-free method for modeling of multi-atomic systems using results of Kohn-Sham calculations for single atoms. We have obtained equilibrium bond lengths and binding energies for dimers Li2, Be2, B2, C2, N2, O2, F2, Na2, Mg2, Al2, Si2, P2, S2 & Cl2, as well as for C3, C24 and C60 systems in good accordance to other theoretical and experimental data.
