The property of a 2dimensional 2electron quantum dot (QD) subjected to an external magnetic field B and affected by a charged impurity is studied. The impurity is located at the zaxis by a distance d from the plane of the dot. The energy spectra of lowlying state of the QD are obtained by the exact diagonalization approach. The evolution of the angular momentum L0 and the spin S0 of the ground state in accord with B and d has been calculated
the results are summarized and plotted in a (L0
S0) diagram. The (L0
S0) diagram indicates that the transitions of L0 and S0 are matched in peculiar way.
