Elastic Form Factors in Point-form Approach
Using the point-form approach to relativistic quantum mechanics, a covariant framework is presented for the calculation of proton and neutron electromagnetic form factors. Results for charge radii, magnetic moments, and electric as well as magnetic form factors are produced using the wave functions obtained in the socalled Goldstone-boson-exchange constituent quark model. All the predictions ar...
متن کاملElastic Form Factors of the Proton, Neutron and Deuteron
In this paper an overview of past and future measurements of the elastic nucleon and deuteron electromagnetic form factors and a comparison with a selection of theoretical descriptions is provided.
متن کاملNeutron Form Factors from Quasi-Elastic Electron-Deuteron Scattering
The differential cross section for quasi-elastic electron-deuteron scattering has been measured at the Cambridge Electron Accelerator in the four-momentum-transfer region from 7 to 115 PfC0.27 to 4.47 (Bev/~)~] . The method used involved a coincidence between scattered electrons and recoiling protons. Electrons without a high-energy proton in coincidence were assumed to be due to a neutron inte...
متن کاملFront-form calculation of the deuteron EM form factors
The deuteron form factors are calculated in the framework of the relativistic nucleon-meson dynamics. The relativistic effects change considerably the Sand D-waves of the deuteron, result in the dominating extra component in the deuteron wave function and generate the contact interaction between the nucleon, mesons and photon. The prediction for the polarization observable t20 is in good agreem...
متن کاملThe Nucleon Elastic Form Factors
The nucleon elastic form factors are of fundamental interest, provide a unique testing ground for QCD motivated models of nucleon structure and are of critical importance to our understanding of the electromagnetic properties of nuclei. I review the recent experimental effort to measure the nucleon elastic form factors.
