Magnetospectroscopyof a highly excited single InAs-GaAs quantum dot is performed.The multiexcitonic emission related to the s, p, and dshells of a zero-dimensional system is identified. Orbital Zeeman effectsfor the p and d energy shells are observed. Theoverall pattern of the magnetic field evolution of the emissionlines resembles a single-particle Fock-Darwin diagram. Effects of interaction betweenthe multiexcitonic configurations and the asymmetry of localizing potential areclearly visible when single-particle states become nearly degenerate: at B=0and at a level crossing induced by the magnetic field.
