Abstract
We first consider N Coulombically interacting electrons confined within a sphere of radius R by an infinite potential barrier. Scaling properties of the Hamiltonian are first discussed, followed by the virial theorem. In the limit of large R and N, it is shown that the problem can be reduced to the solution of N point charges -\e\ constrained to move on the surface of a sphere of radius R-W here defined as Wigner radius. Finally, the results of the above model are compared with those of harmonically confined electrons. (C) 2004 Elsevier B.V. All rights reserved.
