Magnetic form-factors by 180° electron scattering
Physics Letters, 1962Elastic magnetic scattering peaks resulting from the scattering of 41.5- Mev. electrons through 180 deg are shown for Li/sup 6/ and Li/sup 7/. Cross sections are (4 plus or minus 2) x 10/sup -33/ and (5.8 plus or minus 0.4) x 10/sup -32/ cm/sup 2//sr for Li/sup 6/ and Li/sup 7/, respective ly.

Fine structure in the dynamic form factor of an electron liquid
Physical Review B, 1984Using a simple model for the quasiparticle damping, we show how the fine structure observed in the dynamic form factor of an electron liquid can be understood on purely kinematic considerations. We also show that more realistic calculations of the self-energy including vertex corrections leave the qualitative features of the model unchanged.

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 ...

Three-pion form factor from electron-positron experiments
Il Nuovo Cimento, 1961The reaction e+ + e- yields + + pi - + pi 0 mentally, following preliminary calculations based on previous work (N. Cabibbo and R. Gatto, Phys. Rev. Letters 4, 3l3(l960)). A 3 pi resonance peak was found at E 525 Mev.

Electron form factors up to fourth order. - I
Il Nuovo Cimento A, 1972The explicit results of the analytic evaluation of the discontinuities of the electron form factors and of their zero-momentum-transfer values, up to the fourth order of the perturbative expansion of QED in the electric charge, are presented. Asymptotic and threshold behaviours are discussed.

Electron-Scattering Form Factors and Nuclear Transition Densities
1991Electron scattering is a very useful method for investigating nuclear structure. Since the electromagnetic interaction is fully known, the only unknowns in the description of the reaction are the nuclear (transition) charge and current densities, which can be determined by analyzing the experimental data.

Nucleon electromagnetic form factors from scattering of polarized muons or electrons
Physical Review C, 1987We investigate a new method of extracting nucleon form factors by using measured asymmetries of polarized leptons scattered off polarized targets. Systematic errors can be eliminated that way, unlike the conventional analysis via Rosenbluth plots. The kinematics can be chosen such that the asymmetry receives contributions selectively from either ${G}_ ...

Form-Factors of Relativistic Electron Bunches in Polarization Radiation
Advanced Materials Research, 2015The formalism of form factors is the basis for the describing the coherent radiation of bunches that comprise relativistic charged particles. The general theory of coherent radiation for synchrotron and bremsstrahlung radiation, when radiation is generated directly by charged particles, but not by the material of a target, was developed long ago ...

Electronic health record on the go: Device form factor and Fitts’ law
International Journal of Medical Informatics, 2018With electronic health records (EHRs) becoming ubiquitous, computer use in exam rooms during patient-provider interactions is commonplace. Although computer use brings many benefits to providers, and patients generally rate computer-use as having a positive impact, the use of mobile devices could eliminate existing issues, for example allowing ...
