Abstract
The relativistic effective mass and Fermi momentum are important ingredients in the determination of the nuclear equation of state, but they have rarely been extracted from experimental data below saturation density where translationally invariant nuclear matter becomes unstable against clusterization into the existing atomic nuclei. Using a novel kind of superscaling analysis of the quasielastic cross-section electron scattering data involving a suitable selection criterion and as a reference nucleus, the global scaling properties of the resulting set of data for 21 nuclei ranging from to are then analyzed. We find that a subset of a third of the about 20000 data approximately scales to an universal superscaling function with a more constrained uncertainty band than just the reference case and provides as a function of .
