摘要：

Ion and electron ordered clusters in 3D and 2D traps are considered. These systems under some conditions are the physical realization of the Thomson atom. At low temperatures clusters have a shell structure with an angle order inside the shells. The table for Thomson atoms was computed. Melting corresponding to the relative rotation of the shells with respect to each other in 2D clusters was found. Melting of 3D clusters begins in oner or more spherical shells while the shell structure remains. © 1990.
