Query: Nucleon momentum distribution extracted from the experimental scaling
  function   The connection between the scaling function, directly extracted from the
analysis of electron scattering data, and the nuclear spectral function or
nuclear momentum density is investigated at depth. The dependence of the
scaling function on the two independent variables in the scattering process,
the transfer momentum ($q$) and the scaling variable ($y$), is taken into
account, and the analysis is extended to both, positive and negative
$y$-values, i.e., below and above the center of the quasielastic peak,
respectively. Analytical expressions for the derivatives of the scaling
function, evaluated at the finite limits of integration dealing with the
kinematically allowed region, are connected with the spectral function. Here,
contributions corresponding to zero and finite excitation energies are
included. The scaling function is described by the Gumbel density distribution,
whereas short-range correlations are incorporated in the spectral function by
using some simple models. Also different parametrizations for the nucleon
momentum distribution, that are compatible with the general properties of the
scaling function, have been considered.
