Query: Relativistic y-scaling and the Coulomb sum rule in nuclei   In this paper dividing factors GL and GT are constructed for the longitudinal
and transverse responses of the relativistic Fermi gas in such a way that the
reduced responses so obtained scale. These factors parallel another dividing
factor studied previously, HL, that yields a (different) reduced response which
fulfills the Coulomb sum rule. GL, GT and HL are all found to be only very
weakly model-dependent, thus providing essentially universal dividing factors.
To explore the residual degree of dependence which remains, the scaling and sum
rule properties of several specific models have been considered. It is seen
that the relativistic Fermi gas (by construction) and also typical shell-model
reduced responses successfully scale and satisfy the Coulomb sum rule, as do
experimental results at medium to high momentum transfers. On the other hand,
it is observed that the quantum hadrodynamic model does so only if interaction
effects become weaker with increasing momentum transfer, as predicted in the
most recent versions of that model.
