  The superscaling observed in inclusive electron scattering is described
within the dilute Fermi gas model with interaction between the particles. The
comparison with the relativistic Fermi gas (RFG) model without interaction
shows an improvement in the explanation of the scaling function $f(\psi ')$ in
the region $\psi ' < -1$, where the RFG result is $f(\psi ') = 0$. It is found
that the behavior of $f(\psi ')$ for $\psi ' < -1$ depends on the particular
form of the general power-law asymptotics of the momentum distribution
$n(k)\sim 1/ k^{4+m}$ at large $k$. The best agreement with the empirical
scaling function is found for $m\simeq 4.5$ in agreement with the asymptotics
of $n(k)$ in the coherent density fluctuation model where $m = 4$. Thus,
superscaling gives information about the asymptotics of $n(k)$ and the NN
forces.
