Abstract

The (e, e'p) reaction on 12C, 28Si, 40Ca and 58Ni has been measured at 497 MeV incident electron energy. The experiment covered the region E ≦ 80 MeV for the separation energy and P ≦ 250 MeV/ c for the recoil momentum. Cross sections, calculated in the distorted wave impulse approximation, have been utilized in a shell-model expansion of the spectral function. Average separation and kinetic energies of protons in individual shells are extracted from the data. The validity of Koltun's sum rule is discussed.
