| Influence of magnetic field on the energy positions and widths of one electron resonance states in a multi-shell spherical quantum dot is investigated. The one-band effective mass approximation is assumed. The complexeigenvalue Schrodinger equation approach involving complex rotation of coordinates is used to obtain complex eigenenergies, Er - iΓ/2, corresponding to resonance states. We show how the magnetic field changes the resonance energy, Er, and decay rate, Γ, yielding bound states for some particular cases. |
