The charge density and pair correlation function of three interacting electrons confined within a two-dimensional disc-like hard-wall quantum dot are calculated by full numerical diagonalization of the Hamiltonian. The formation of a Wigner molecule in the form of equilateral triangular configuration for electrons is observed as the size of the dot is increased. (C) 1999 Elsevier Science B.V.
