Molecular dynamics simulations were used to investigate the lowest-energy state of spherical clusters made up of single-species charged particles in a three-dimensional confining potential. The energy per particle of shell-structured clusters was compared to that of spherical finite-bcc lattice with relaxed surfaces. The formation of small bcc lattice (nucleation) was observed in the shell-structured cluster of 2×104 ions.
