Abstract
Energy spectra of superconducting nanospheres observed via tunneling spectroscopy are theoretically discussed. In the energy gap we find small peaks which correspond to the two-particle dynamics beyond the mean-field BCS approximation. These peaks promise to be a sensitive test of theories of superconductivity as their number and positions depend on the approximation used.
