Quasielastic electron scattering

Physical Review C, 1974
Data and interpretation are presented for inelastic electron scattering in the quasielastic region from nine target nuclei ranging from lithium to lead at an incident energy of 500 MeV and a scattering angle of 60\ifmmode^\circ\else\textdegree\fi{}. The average kinetic and separation energies of nucleons in these nuclei are deduced.

Quasielastic scattering in PrAl3

Physica B: Condensed Matter, 1997
Abstract Using the long-wavelength polarisation analysis neutron spectrometer (LONGPOL) fitted with time-of-flight analysis, the crystal field excitation spectrum of the rare earth trialuminide PrAl 3 was measured, and transitions of 4.5 and 3.7 meV were observed to take place between states of the Pr 3+ ion.

Parity-violating quasielastic electron scattering

Nuclear Physics A, 1992
Abstract Parity-violating quasielastic electron scattering from nuclei is studied within the context of the relativistic Fermi gas model. Three issues are discussed: (i) the merits of such studies for obtaining new information about single-nucleon form factors, especially the roles played by the axial-vector and strangeness form factors, (ii) the ...

Quasielastic light scattering in silicon [PDF]

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.

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 ...

Pionic effects in quasielastic electron scattering

Nuclear Physics A, 1990
Abstract Quasielastic electron scattering from nuclei at high momentum transfer and energy loss is approached using a model which incorporates specific classes of effects arising from the exchange of pions between nucleons in the nucleus. Building on the (purely nucleonic) relativistic Fermi gas responses, pionic effects in 1p1h correlation and meson

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.

Quasielastic Light Scattering from Diamond

Physical Review Letters, 1985
Strong quasielastic features have been found in light scattering from diamond in the frequency range 0 to \ifmmode\pm\else\textpm\fi{} 200 GHz and have been investigated as a function of wave-vector transfer ($Q$) and temperature ($T$). The evolution of a relatively narrow Lorentzian component (\ensuremath{\sim} 10 GHz) demonstrates for the first time ...

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 ...
