Abstract
We perform large-scale molecular dynamics (MD) simulations of Coulomb clusters in a spherical trapping field. The fast multipole method have been employed to simulate clusters of up to 5 × 104 particles while previous investigations are limited to clusters of less than 5000 particles. It is found that the Madelung energy of bcc clusters with reconstructed surfaces is substantially smaller than the extrapolated values based on the previous results for smaller multilayered icosahedral clusters.
