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.
