C12(e,ep)Results as a Critical Test of an Energy Sum Rule

Abstract
The reaction C12(e,ep) at 497 MeV in conjunction with a distorted-wave impulse-approximation analysis was used to determine kinetic and separation energies of bound protons. The spectral function for separation energies less than 74 MeV provides only hal of the total binding energy; i.e., the data do not satisfy Koltun's sum rule. The momentum distributions are compatible with elastic electron scattering.
