DISPERSIVE EFFECTS IN HIGH-ENERGY ELASTIC ELECTRON--NUCLEUS SCATTERING AND NUCLEAR CORRELATIONS.

摘要: Abstract The effects of virtual nuclear excitations in high-energy elastic electron-nucleus scattering are analyzed a self-consistent manner. We describe the by an infinite system coupled equations which we solve semiclassical approximation. resulting amplitude is explicity expressed terms one- and two-body densities. dispersion corrections then directly related to nucleon-nucleon correlations. To investigate above ideas study 420 MeV 840 Mev electrons 16 O 208 Pb. dispersive most pronounced diffraction minima small elsewhere, slightly energy momentum-transfer dependent, unlikely be reproduceable changes charge density. Even if were experimentally measureable, it would still extremely difficult extract from them information about dynamical short-range correlations because entangled with Pauli correlations, self-correlations, differences excited states. also show that may obtained solving pair or simple Dirac equation effective optical potential critically compare approaches.
