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...
متن کاملParity Violation in Polarized Electron Scattering
Parity violation has been well established in particle physics for many years, since the 1950's where it was. first seen in beta decay processes. The strong and electromagnetic forces are parity conserving, and the experimental evidence that parity was not conserved in weak processes came somewhat as a surprise. The weak forces are responsible for the decay of radioactive nuclei, and it was in ...
متن کاملParity violation in quasifree electron scattering off the deuteron
For deuteron electroweak disintegration, parity violating effects are investigated which arise from the interference of γ and Z exchange as well as from the hadronic sector via a small parity violating component in the deuteron. The general formalism for the differential cross section and polarization observables of electromagnetic deuteron disintegration is extended to incorporate parity viola...
متن کاملNuclear 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...
متن کاملFurther Tests of Parity Violation in Inelastic Electron Scattering
Further measurements of parity violating asymmetries in inelastic scattering of polarized electrons from deuterium have been made for a range of y values from 0.15 to 0.36. Only a small y-dependence is observed in the asymmetries. Using the quark-parton model our results are in good agreement with the Weinberg-Salam predictions. 0.020. We obtain a value of the parameter sin2f3W= 0.224 ?r The ev...
