Absorptive form factors for high-energy electron diffraction
Acta Crystallographica Section A Foundations of Crystallography, 1990The thermal diffuse scattering contribution to the absorptive potential in high-energy electron diffraction is calculated in the form of an absorptive contribution to the atomic form factor. To do this, the Einstein model of lattice vibrations is used, with isotropic Debye-Waller factors.

Electron scattering form factors for fp-shell nuclei
Nuclear Physics A, 1985Abstract Elastic and inelastic electron-scattering form factors for multipolarities up to L = 7 and some transition-strength distributions are calculated with shell-model wave functions for about ten target nuclei in the mass range A = 52–62. The results are compared with the available measured transition strengths and (e, e') form factors.

Thermal Optimization of Electronic Equipment: Form Factor Improvement
2009 Third UKSim European Symposium on Computer Modeling and Simulation, 2009The need to have equipments with a low form factor, defined as depth divided by the width multiplied by the height, is very essential for a particular product to be marketable. Thus, when an old product needs to be customized to a new form factor, while maintaining the standardized components, there will be distorted thermal distribution. In this study,

Neutron Form Factors from Inelastic Electron-Deuteron Scattering
Physical Review, 1965The electromagnetic form factors of the neutron have been measured in the ${q}^{2}$ range from 1.0 to 30.0 ${\mathrm{F}}^{\ensuremath{-}2}$. It is found that for values of ${q}^{2}$ greater than about 6.0 ${\mathrm{F}}^{\ensuremath{-}2}$ the square of the neutron's charge form factor ${({G}_{\mathrm{En}})}^{2}$ is consistent with zero to within an ...

Neutron Form Factors from Inelastic Electron-Deuteron Scattering
Physical Review, 1964The differential cross section for quasielastic scattering of electrons from neutrons initially bound in deuterium has been measured at 90\ifmmode^\circ\else\textdegree\fi{} and 120\ifmmode^\circ\else\textdegree\fi{} laboratory angle for values of the four-momentum transfer squared equal to 11, 15, 20, 25, and 35 ${\mathrm{F}}^{\ensuremath{-}2}$.

Proton Form Factors from Elastic Electron-Proton Scattering
Physical Review, 1966Absolute measurements of the elastic electron-proton cross section have been made with a precision of about 4% for values of the square of the four-momentum transfer, ${q}^{2}$, in the range 6.0 to 30.0 ${\mathrm{F}}^{\ensuremath{-}2}$ and for electron scattering angles in the range 45\ifmmode^\circ\else\textdegree\fi{} to 145\ifmmode^\circ\else ...

On the dynamic form factor of an electron liquid
Solid State Communications, 1974Abstract The mean field theories of an electron liquid at metallic densities, which go beyond the RPA, and which have been fairly successful so far, are shown to be inadequate when tested against phenomena involving high frequencies. It is also shown that by making a simple Gaussian ansatz for the imaginery part of the response function, χ″(q,ω), and

Neutron Form-Factor Measurement Using Electron-Neutron Coincidences
Physical Review Letters, 1962An electron-deuteron inelastic scattering experiment was performed at incident electron energies of 620 and 350 Mev. The ratio of electron-neutron to electron-proton coincidences was measured at two scattering angles for the interaction e + d yields e + n + p. The data were analyzed in terms of the alternative form factors G/sub E/ and G/sub M/.

Magnetic form factor of electrons in 3d bands
AIP Conference Proceedings, 1975The formalism for calculating the spin density or magnetic form factor for tight‐binding band electrons is considered in the case where nearest‐neighbor overlap is not negligible. The formalism leads to a description of the system in terms of a two‐component form factor, one of which is identical to the atomic form factor and the other is related to ...
