摘要：

The ground-state configurations of a two-dimensional cluster of classical charged particles which are confined by an external ring harmonic potential are determined. With increasing number of particles (N) different structural transitions are found. First, the ring arrangement of particles undergoes a zig-zag transition. Further increasing N, more rings are formed which exhibit one-dimensional crystal-like structures. A normal mode analysis of the ground-state configuration is performed, from which we obtain information on the stability of the ring cluster.
