Structure and Madelung Energy of Coulomb Clusters

Abstract

The ground state of the system of charged particles of one species confined by the three dimensional, isotropic, and parabolic potential is investigated by molecular dynamics simulations. It is shown that, with the increase of the system size or the number of particles in the system N, the ground state changes from the shell-structured system to the finite bcc lattice with reconstructed surface. The critical value of the transition is estimated to be between N = 10(exp 4) and N = 2 x 10(exp 4). The nucleation of the bcc lattice in the shell-structured cluster of 2 x 10(exp 4) ions is observed.
