ABSTRACT

We report on selfconsistent microscopic calculations of the electronic shell and supershell structure of sodium clusters with up to N ∼ 3000 atoms. The spherical jellium model in local density approximation is used and the Kohn-Sham equations are solved numerically. The finite temperature of the valence electrons is included by treating them as a canonical subsystem embedded in the heat bath of the ions. In particular, we evaluate the total free energy F(N) and investigate its fluctuating part, the shell-correction energy F(N), as a function of temperature T and particle number N. We also discuss the second difference Δ2F(N) = F(N+1)+ F(N - 1) - 2F(N) and its relation to the recently measured cluster mass abundance spectra. More... »
