The experimental dynamic and static longitudinal structure factors of 12C, 40Ca and 56Fe are investigated with a semiclassical RPA theory. The ph interaction is linked at zero momentum to the nuclear compression modulus and symmetry energy. Its momentum evolution is handled phenomenologically, as well as the position-dependent nucleon effective mass. Quite reasonable values of these quantities allow a satisfactory account of the experimental data over a wide range of momentum transfers in all the three nuclei. In order to achieve this result the proton root mean square radius has to be increased of about 13% in 12C, 23% in 40Ca and 21% in 56Fe.

Abstract
The experimental dynamic and static longitudinal structure factors of 12C, 40Ca and 56Fe are investigated with a semiclassical RPA theory. The ph interaction is linked at zero momentum to the nuclear compression modulus and symmetry energy. Its momentum evolution is handled phenomenologically, as well as the position-dependent nucleon effective mass. Quite reasonable values of these quantities allow a satisfactory account of the experimental data over a wide range of momentum transfers in all the three nuclei. In order to achieve this result the proton root mean square radius has to be increased of about 13% in 12C, 23% in 40Ca and 21% in 56Fe.
