We investigate theoretically Raman spectra of few-electron quantum dots. Spectra obtained by an exact many-body treatment and by a time-dependent local-density approximation are compared. We show that single-particle-like excitations can be expected for systems with only six electrons. The energies of these excitations are close to the Kohn-Sham level spacings.
