摘要：
The ground-state energies of several interacting electrons (N less than or equal to 12) confined in a parabolic quantum dot with an impurity ion at the centre are obtained by numerical diagonalizations. Series of magic values of angular momentum are determined. The rules for identifying the magic numbers are established.
