Abstract

We report on empirical parameterizations of longitudinal (\cal R_L) and transverse (\cal R_T) nuclear electromagnetic form factors for elastic scattering and the excitations of nuclear states in \rm ²⁷Al and \rm ⁴⁰Ca. The parameterizations are needed for the calculations of radiative corrections in measurements of electron scattering cross sections on \rm ²⁷Al and \rm ⁴⁰Ca in the quasi-elastic, resonance and inelastic continuum regions, provide the contribution of nuclear excitations in investigations of the Coulomb Sum Rule, and test theoretical model predictions for excitation of nuclear states in electron and neutrino interactions on nuclear targets at low energies.
