| Abstract: | We calculate the energy levels of low-lying states of a two-electronquantum ring under the influence of perpendicular homogeneous magnetic field.Calculations are made by using the method of exact diagonalization withinthe effective-mass approximation. The ground-state electronic structures andangular momentum transitions as a function of the strength of a magneticfield have been revealed. |
