Laplacian field of the effectively unpaired electron density: Determination of many-body effects on electron distributions
(American Chemical Society, 2007-12)
This work carries out the study of the Laplacian field function of the electron density L(r) = -∇2ρ(r) splitted in two contributions ρ(r) = ρ(p)(r) + ρ(u)(r), which correspond to the effectively paired and effectively ...
Studies of threshold effects in the interaction of protons, electrons, and positrons in matter using dielectric models
(Elsevier Academic Press Inc, 2019-06)
A review of the behavior of the energy loss, mean-free path and straggling of protons, positrons, and electrons in an electron gas is performed using different dielectric models which represent the case of metals (Lindhard ...
A long way to the electrode: how do Geobacter cells transport their electrons?
(Portland Press, 2012-12-01)
The mechanism of electron transport in Geobacter sulfurreducensbiofilms is a topic under intense study and debate. Although some proteins were found to be essential for current production, the specific role that each one ...
CDW theoretical description of the single ionization of argon by positron and electron impact
(Elsevier Science, 2007-08)
In this work, we consider the single ionization of Ar by 200 eV positron and electron impact. The quantum mechanical continuum distorted wave (CDW) model is used in the one-active electron approximation. Parametrizations ...
Evaluation of differential cross sections using classical two-active electron models for He
(Springer, 2019-01-10)
Differential cross sections for charge-exchange and single and double electronic emission in collisions of protons with He atoms at intermediate impact energies are theoretically evaluated by means of two classical trajectory ...
Energy and electron spectra after grazing- ion-surface collisions
(American Physical Society, 2002-12)
For ions that impinge grazing on solid surfaces, binary collisions with the free-electron gas are investigated by means of a modified specular-reflection (MSR) model. The proposed MSR theory is applied to the calculation ...
Multiple scattering of charged particles in a free electron gas
(American Physical Society, 2006-12)
We study the influence of electron-scattering processes on the angular distributions of point particles moving through a free-electron gas. Previous calculations for slow ions are extended to all (nonrelativistic) velocities. ...
Electron emission in grazing-ion-surface collisions
(American Physical Society, 2000-12)
For ions impinging grazingly on a solid surface, the electron emission from the inner shells of solid atoms is investigated by employing a semiclassical formalism. The emission rate is expressed in terms of probabilities ...
Modulation of Functional Features in Electron Transferring Metalloproteins
(Centro de Estudios sobre Ciencia, Desarrollo y Educación Superior, 2020-03)
Electron transferring metalloproteins are typically implicated in shuttling electrons between energy transduction chains membrane complexes, such as in (aerobic and anaerobic) respiration and photosynthesis, among other ...
Analog pile-up circuit technique using a single capacitor for the readout of Skipper-CCD detectors
(IOP Publishing, 2021-11)
With Skipper-CCD detectors it is possible to take multiple samples of the charge packet collected on each pixel. After averaging the samples, the noise can be extremely reduced allowing the exact counting of electrons per ...
