Precision Measurement of Longitudinal and Transverse Response Functions of Quasi-Elastic Electron Scattering in the Momentum Transfer
نویسندگان
چکیده
We propose to make a precision measurement of inclusive electron scattering cross sections in the quasi-elastic region for a wide range of momentum transfers for He, C, Fe and Pb. We will extract the longitudinal and transverse response functions in the momentum transfer range 0.55 GeV/c ≤ |q| ≤ 0.9 GeV/c with a precision of a few percent improving significantly on the precision of previous measurements in the overlap region. This should allow us to confirm/refute the presently controversial issue of the quenching of the longitudinal response function in medium weight nuclei and as importantly investigate the |q| evolution of the Coulomb Sum Rule as we probe significantly shorter distances.

Longitudinal and Transverse Quasi-Elastic Response Functions of Light Nuclei
The He and He longitudinal and transverse response functions are determined from an analysis of the world data on quasi-elastic inclusive electron scattering. The corresponding Euclidean response functions are derived and compared to those calculated with Green’s function Monte Carlo methods, using realistic interactions and currents. Large contributions associated with two-body currents are fo...
متن کاملA resolution of the missing charge problem in quasielastic electron scattering
At high momentum transfer jqj > 1GeV, the longitudinal response in quasielastic electron scattering is well reproduced by the free Fermi gas model. This suggests the suppression of the Z-graph contributions in elementary electron-nucleon scattering in nuclear medium. Therefore we develop the relativistic model in which those contributions are partially suppressed. The suppression rede nes the r...

It is proposed that extraction of the scaling function F(y) from the transverse and longitudinal response functions in inclusive quasi-elastic electron scattering from 3He and 4He is a powerful method to either study the validity regime of the impulse approximation by allowing the access to the high nucleon momentum components in these nuclei, or the electromagnetic properties of bound nucleons.

متن کاملMeasurement of elastic electron-neutron scattering and inelastic electron-deuteron scattering cross sections at high momentum transfer.
We have measured inelastic electron-deuteron, electron-proton, and electron-aluminum cross sections at 10' in the kinematic region between-elastic deuteron scattering and the second resonance region at six beam energies between 9.8 and 21 GeV. The elastic electron-neutron cross section was extracted from the quasi-elastic data at Q2 = 2.5, 4.0, 6.0, 8.0 and 10.0 (GeV/c)'. The ratio of elastic c...
