Low energy scattering of positrons by H2O
(Elsevier Science BvAmsterdamHolanda, 2010)
Incoherent scattering by free electrons as a technique for studying the ionosphere and exosphere: observations and theoretical considerations
(National Institute of Standards and Technology, 1959-09-18)
Incoherent scattering by the free electrons of the ionosphere has been predicted and offered as a technique for measuring the electron density profile both below and above the F region maximum. This paper reports observations ...
Electron and hole scattering in short-period 'IN'GA'AS'/'IN'P superlattices
(American Institute of Physics - AIPCollege Park, 2011-10)
The combination of photoluminescence and magneto-transport measurements is used to study the single-particle relaxation time and the transport scattering time in short-period InGaAs/InP superlattices. Both the single-particle ...
Multiple scattering of slow ions in a free electron gas
(American Physical Society, 2005-12)
We study the influence of electronic scattering on the angular distributions of ions and atoms moving through a free-electron gas. We present a general formulation based on the multiple-scattering formalism, using two ...
Electronic excitation of H-2 by positron impact

Variational calculation of positronium-helium-atom scattering length
(2001-08-01)
A basis-set calculation scheme for S-waves Ps-He elastic scattering below the lowest inelastic threshold was formulated using a variational expression for the transition matrix. The scheme was illustrated numerically by ...

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. ...
Electronic correlation effects on the neutralization of Ga+ scattered by a gold surface
(American Physical Society, 2017-08)
The monotonous increasing with temperature behavior of the neutralization of Ga+ scattered by a gold surface plus the nonmagnetic character of the ion induced to disregard the important electronic correlation effects. In ...
