Nucleon Momentum Distributions from a Modified Scaling Analysis of Inclusive

Inclusive electron scattering from nuclei at low momentum transfer (corresponding to x ≥ 1) and moderate Q is dominated by quasifree scattering from nucleons. In the impulse approximation, the cross section can be directly connected to the nucleon momentum distribution via the scaling function F (y). The breakdown of the y-scaling assumptions in certain kinematic regions have prevented extraction of nucleon momentum distributions from such a scaling analysis. With a slight modification to the y-scaling assumptions, it is found that scaling functions can be extracted which are consistent with the expectations for the nucleon momentum distributions.
