Excitation of two interacting electrons as a plasmon-decay mechanism in proton-aluminum collisions
(American Physical Society, 2004-12)
Projectile-induced plasmon excitation in an electron gas has been studied by several authors who proposed two possible mechanisms for these plasmons to decay. In a previous work we considered one of these mechanisms in ...
Low-energy electron collisions with acetic acid

Theory of ionization processes in positron-atom collisions
(Elsevier Science, 2006-12)
We review past and present theoretical developments in the description of ionization processes in positron-atom collisions. Starting from an analysis that incorporates all the interactions in the final state on an equal ...
Split-beam studies of the effect of electron collisions on ISR spectra near k ⊥ B
(Instituto Geofísico del Perú, 2000)
In an effort to test these models, we divided the Jicamarca radar into two beams, each with half the power and half the antenna of the full system, and ran the standard double pulse Faraday/ ACF mode that gives ACFs in the ...
Electron excitation after plasmon decay in proton-aluminum collisions
(American Physical Society, 2003-12)
When a projectile travels inside a metal, it interacts with the electron gas, producing both binary and collective excitations ~plasmons!. Within the nearly-free-electron-gas scheme, Ro¨sler and co-workers showed that ...
X-ray emission produced in charge-exchange collisions between highly charged ions and argon: Role of the multiple electron capture
(American Physical Society, 2014-12)
In this work we use the classical trajectory Monte Carlo method within an eight-electron scheme to theoretically study photonic spectra that follow charge-exchange processes between highly charged ions of charge states ...
On a proper electron collision frequency for a Fokker–Planck collision model with Jicamarca applications
(Elsevier, 2004-11)
Recently, Sulzer and Gonzalez (J. Geophys. Res. 104 (22) (1999) 22, 535) showed that the previously neglected effect of electron–electron and electron–ion Coulomb collisions has a significant impact on determining the ...
Angular differential studies of electron transfer in collisions of He-like ions with Na(3s): The role of electron saddle crossings
(American Physical Society, 2013-03-20)
We present a systematic experimental and theoretical study of angular differential cross sections of singleelectron transfer in collisions of N5+, O6+, and Ne8+ with ground-state Na(3s) in the collision energy range from ...
Grazing Ion-Surface Collisions
(IOP Publishing, 2004-01)
Electron emission after grazing ion-surface collisions is studied for high impact velocities. We have focused on glancing angles of electron emission where the dominant mechanism is the ionization from atomic bound states. ...
