Absorptive form factors for high-energy electron diffraction [PDF]
The 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.

Magnetic form factor for itinerant-electron systems
Physical Review B, 1994First-principles calculations of the itinerant-electron magnetic form factor for ferromagnets which include both the spin and orbital contributions have been completed for ferromagnetic nickel and iron. To our knowledge, these are the first calculations of this type for 3[ital d] ferromagnets.

Electron-scattering form factors for the giant dipole resonance [PDF]
Using a previously developed formalism based on the generator coordinate method, the longitudinal- and transverse-excitation form factors for the giant dipole resonance are obtained. Although microscopically established, that approach can provide analytic and compact expressions for some selected closed-shell nuclei.

Form Factors in Electron-Trinucleon Scattering
Physical Review, 1965Abstract : The four form factors in electron-trinucleon (e-H3 or e-He3) elastic scattering are analyzed using two alternative sets of four unknowns: (i) the neutron electric form factor, the form factor F for the dominant S state and the isovector- and isocalar-exchange magnetic form factors-neglecting the mixed symmetry S' state; (ii) the form factors

Form factors for electron scattering on 10B and 11B
Nuclear Physics A, 1978Abstract The form factors for elastic scattering of electrons by 10 B and 11 B and the inelastic form factor to the 6.02 MeV level in 10 B are calculated with intermediate coupling wave functions in a projected Hartree-Fock basis. Good agreement with experiment is obtained.

Paramagnetic form factors for cubic itinerant electron systems
Physical Review B, 1988Measurements of the elastic neutron scattering cross section performed over the past several decades have provided information about the induced magnetic form factor for a number of transition-metal paramagnets. These results, when converted to an absolute scale, provide a sensitive test of electronic wave functions obtained from band calculations ...

Suppression of elastic magnetic electron scattering form factors
Physical Review C, 1985Some recent experiments have reported a strong suppression of the M3 part of the elastic magnetic electron scattering in a number of light nuclei. We examine the effect of the first-order as well as second-order perturbative diagrams on the momentum-transfer dependence of the M1 and M3 form factors in the case of a closed f/sub 7/2/ shell plus a ...

X-ray form factors and the electronic structure of graphite
Physical Review B, 1982The bonding and spectroscopic properties of graphite are investigated by carrying out first-principles, self-consistent electronic structure calculations, and by comparing the results with high-resolution data from recent x-ray diffraction and angle-resolved photoemission measurements.

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,

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.
