Quasielastic electron scattering from nuclei: Random-phase vs ring approximations

We investigate the extent to which the nuclear transverse response to electron scattering in the quasielastic region, evaluated in the random-phase approximation, can be described by ring approximation calculations. Different effective interactions based on a standard model of the type g81Vp1Vr are employed. For each momentum transfer, we have obtained the value of g08 permitting the ring respo...

Relativistic pionic effects in quasielastic electron scattering

The impact of relativistic pionic correlations and meson-exchange currents on the response functions for electromagnetic quasielastic electron scattering from nuclei is studied in detail. Results in first-order perturbation theory are obtained for one-particle emission electronuclear reactions within the context of the relativistic Fermi gas model. Improving upon previous analyses where non-rel...

Nuclear Fermi Momenta from Quasielastic Electron Scattering

presented in Fig. 3(b). Weber and Seavey' have measured the uniform resonance nuclear relaxation rates in RbMnF, over the dc field range of 6-23.5 kOe at T=4.2 K. They observed a similar frequency dependence of these rates to the dependence shown ln Flg. 3(a), namely, a decrease in magnitude with increasing magnon frequency. By extrapolating their results to the frequency range presented in the...

Effective interaction in quasielastic electron scattering calculations

The transverse nuclear response for quasifree electron scattering is discussed. The analysis is done by comparing different calculations performed in the random-phase approximation and ring approximation frameworks. The importance of the exchange terms in this energy region is investigated and the changes in the nuclear responses due to the modification of the interaction are evaluated. The cal...
