A scaling function for inclusive electron scattering was constructed [1] within the Coherent Density Fluctuation Model (CDFM) [2]. The latter is a natural extension to finite nuclei of the Relativistic Fermi Gas Model within which the scaling variable psi' was introduced [3]. It was shown that the high-momentum components of the nucleon momentum distributions in the CDFM and their similarity for different nuclei explain quantitatively the superscaling in nuclei for negative values of psi', including also those smaller than psi'<-1.References
