  In the paper, we present theoretical calculations of the cross section for
inelastic light scattering by electronic excitations in a quantum dot charged
with 42 electrons. The many-electron states involved in the computations are
obtained in the framework of the Random Phase Approximation. The evaluation of
energy-weighted sum rules allowed us to distinguish among single-particle
(SPEs), collective charge (CDEs) and collective spin (SDEs) electronic
excitations. Raman spectra in polarized and depolarized geometries are computed
for a range of incident laser energies. The below-band-gap excitation regime
reveals advantages for the identification of individual excited states
contributing to the Raman spectra. The computed polarization ratios for Raman
intensities show the breakdown of selection rules in the presence of a magnetic
field. A new jump rule of Raman intensities at the band gap may help
identifying the nature (charge or spin) of electronic excitations. Under
extreme resonance (laser energy very close to the band gap), Raman spectra are
dominated by SPEs. For incident laser energies 40 -- 50 meV above band gap, a
correct desciption of Raman spectra is shown to require the proper account of
energy widths of intermediate states.
