Effects of the form factor on exclusive (e, e ' p) reactions

For the exclusive (e, e'P) reaction, we discuss the possibility of observin g effects: due to swollen nucleons in the nuclear medium, such as Ca-40 and Pb-208, by introducing form factors of the nucleon in the nuclear medium. These form factors include effectively the change of nucleon properties in the nuclear medium. This: calculation is performed by using a Dirac-Hartree single particle model for a bound state and a relativistic optical model f or a continuum state with inclusion of the electron Coulomb distortion. The effect of the form factor, which increases With higher momentum transfer ( q greater than or equal to 400 MeV/c) is too small to be discerned from the errors on the available experimental data. But it affects the determinatio n of spectroscopic factors to some extent.
