Quasielastic electron scattering in quasiparticle approach

Physical Review C, 1992
A quasiparticle Hamiltonian, which includes the effects of Hartree-Fock and correlations, has been introduced through a parametrization of the radial shape of the effective mass ${\mathit{m}}^{\mathrm{*}}$(r)/m. Within this phenomenological quasiparticle approach the longitudinal and transverse response functions of quasielastic electron scatterings ...

Quasielastic Electron Scattering and Vacuum Polarization

Physical Review Letters, 1989
The longitudinal response function for quasielastic electron scattering from /sup 12/C and /sup 40/Ca at a momentum transfer q = 550 MeV is calculated in a relativistic random-phase approximation (RPA). The particle-hole response is calculated exactly in the finite system while vacuum-polarization effects are included in a local-density approximation ...

Quasielastic light scattering microscope spectrometer

Applied Optics, 1987
We have developed a quasielastic light scattering microscope spectrometer from a commercially available instrument. The coherence requirements of microscope spectrometers have been examined, and our system performs in agreement with theory. Microscopic scattering volumes can be studied while still minimizing spatial averaging effects on the intensity ...

Quasielastic scattering of Li and Be on C

Nuclear Physics A, 2000
Abstract The quasielastic 11 Li, 12 Be + 12 C scattering at E/A≃60 MeV has been studied by adding a fitted polarisation potential to the folding model potential derived from 9 Li, 12 Be - 12 C and neutron- 12 C phenomenological optical potentials. For 11 Li + 12 C scattering

Internal Viscosity and Quasielastic Scattering

The Journal of Chemical Physics, 1971
The hypotheses leading to internal viscosity of polymers are formulated in terms of the neutron incoherent quasielastic scattering law. The mean squared displacement, calculated in the free draining limit, is obtained as an analytical function of the internal viscosity parameter and is shown to decrease uniformly as this parameter increases.

Parity-violating quasielastic electron scattering

Physical Review C, 1993
The parity-violating asymmetry [ital A] is calculated for quasielastic electron scattering. We use a relativistic mean field model of the nuclear matter response. A Lorentz scalar mean field (which reduces the nucleon's mass) decreases [vert bar][ital A][vert bar] by a relatively large amount.

Quasielastic Electron Scattering on 65Cu

AIP Conference Proceedings, 2007
The pioneer method for extraction of quasielastic part from the spectrum of scattered electrons is proposed. The essence of the method is in simultaneous multipole analysis of the mix of quasielastic and resonant formfactors. The identification of resonant peaks and quasielastic part of the formfactor have been held not in scattered electron spectra ...

Scaling in quasielastic electron scattering

AIP Conference Proceedings, 1988
The inclusive (e, e’) cross section on various nuclei in the quasielastic region (Q2/2Mν∼1) has recently been measured in the range 0.25≤Q2≤3.1. Analysis of these data in the plane‐wave impulse approximation allows extraction of a scaling function related to the nucleon momentum distribution.

Quasielastic light scattering in silicon

Journal of Physics C: Solid State Physics, 1984
An investigation of the origin of quasielastic light scattering from silicon surfaces, first observed by Sandercock (1972, 1978) is described. Measurements have been made of the dependence of the quasielastic spectrum upon temperature, wavevector, doping level, and polarisation and intensity of incident light.

Role of strange quarks in quasielastic neutrino scattering

Physical Review C, 1993
Confirming our previous proposal, we show within a continuum random-phase approximation calculation that the ratio of proton-to-neutron neutrino-induced quasielastic yield is a sensitive way to determine the strange quark axial form factor of the nucleon.
