Ks. Chan et Wy. Ruan, Magic angular momenta of a quantum dot under a strong magnetic field: the effect of a Coulomb impurity, J PHYS-COND, 13(25), 2001, pp. 5799-5806
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 th
e centre are obtained by numerical diagonalizations. Series of magic values
of angular momentum are determined. The rules for identifying the magic nu
mbers are established.
