FINITE-SIZE EFFECTS IN A RELATIVISTIC FERMI GAS-MODEL OF QUASI-ELASTIC SCATTERING

Finite-size effects have been incorporated consistently into a relativ istic Fermi gas model of quasi-elastic electron scattering by means of a geometrical correction to the density of states. A simple physicall y meaningful empirical parametrization of the effective radius (or the Fermi momentum) as a function of the mass number is obtained from a f it to experimental differential cross-sections. Using this parameteriz ation of the effective radius the inelastic structure functions and Co ulomb sum rules have been calculated for different nuclei.
