Empirical Fit to electron-nucleus scattering
arXiv:1203.2262
Abstract
An empirical fit to electron-nucleus scattering for $A>2$ is made based on world data. It is valid for $0<W<3.2$ GeV and $0.2<Q^2<5$ GeV$^2$, and can be used with caution at lower $Q^2$. The fit is based on previous empirical fits to electron-proton and electron-neutron scattering, taking into account the effects of Fermi motion plus a substantial extra contribution that fills in the dip between the quasi-elastic peak and the $Î(1232)$ resonance.
