Parametrizations of Electron Scattering Form Factors for Elastic Scattering and Electro-Excitation of Nuclear States for AL-27 and Ca-40

We report on empirical parameterizations of longitudinal and transverse nuclear electromagnetic form factors for elastic scattering and the excitations of nuclear states in AL-27and Ca-40 The parameterizations are needed for the calculations of radiative corrections in measurements of electron scattering cross sections on AL-27 and Ca-40 in the quasi-elastic, resonance and inelastic continuum regions. In addition, they provide the contribution of nuclear excitations to the longitudinal and transverse electromagnetic response functions RL and RT therefore complement measurements of RL and RT in the QE region for comparisons with theoretical models and investigations of the Coulomb Sum Rule
