Abstract. In the framework of the dipole approximation we predict theoretically high magnitudes of: (1) oscillator strength transitions, and (2) the resonance light cattering (sss(w, a)) and absorption (sabs(w, a)) cross-sections. We suggest that these pecularities can be observed experimentally. We discuss the dependence of sabs(w, a) and sss(w, a)) on light frequency w and radius a of the nanoparticle at different physical conditions.
