Emerging charge state after grazing collisions of heavy ions on SnTe surfaces
(American Physical Society, 2000-01)
Emerging charge states of He and Li ions impinging with grazing incidence on a SnTe surface are calculated at high impact velocities. The charge state distribution is obtained as result of the interplay of two atomic ...
CDW-EIS theoretical calculations of projectile deflection for single ionization in highly charged ion-atom collisions
(Elsevier Science, 2003-12)
We present continuum distorted wave-eikonal initial state (CDW-EIS) theoretical calculations for the projectile deflection in single ionization of helium by heavy-ion impact as a function of ionized electron energies. These ...
Comparative studies of the nonlinear effects occurring when highly charged projectiles collide with hydrogen, a free electron gas, and a harmonic oscillator
(American Physical Society, 2005-12)
We calculate the nonlinear effects that appear at the level of the stopping cross section when heavy bare projectiles collide with both atomic hydrogen and a free electron gas. Calculations are carried out by using ...
X-ray emission cross sections following Ar18+ charge-exchange collisions on neutral argon: The role of the multiple electron capture
(American Physical Society, 2011-03)
X-ray emission originating in charge-exchange collisions between Ar18 + and neutral argon is studied at impact energies of 5-4000 eV/amu by means of the classical trajectory Monte Carlo method (CTMC). Line emission and ...
Strong sensitivity of x-ray emission lines following charge exchange between highly charged ions and H(1s) in weakly screened media
(American Physical Society, 2015-11-06)
We use the classical trajectory Monte Carlo method to analyze charge exchange processes between fully stripped projectiles with H(1s) in a screened environment at impact energies in the range 18 eV/amu to 10 keV/amu. For ...
Influence of the projectile charge sign in light particle single ionization of H2O
(Springer, 2019-05)
Positron- and electron-impact ionization of the 1b1 and 3a1 orbitals of H2 O is studied by meansof the CDW-EIS model at an impact energy of 81 eV. Fully differential cross sections are calculated andcontrasted after a ...
Charge Transfer in Low-Energy Collisions of Protons with a Thick C 60 Film
(American Chemical Society, 2020-01)
Charge-exchange processes in collisions between H+ projectiles and a three-monolayer C60 film grown on Cu(111) are experimentally and theoretically analyzed for a wide range of energies (2?8 keV) in the low-energy regime. ...
Ionization of helium by fast and highly charged ions
(Institute of Physics Publishing, 2007-03)
We present CDW-EIS theoretical calculations for the projectile deflection in single ionization of Helium by heavy-ion impact as a function of ionized electron energies. These calculations account for the projectile-residual ...
Cross section scaling for H2O ionization by highly-charged ion impact
(Springer, 2019-02-21)
Electron production following single and multiple ionization of H2O by bare ion impact is theoretically studied by means of the classical trajectory Monte Carlo method. Our results are benchmarked against experimental data ...
Second-order Born collisional stopping of ions in a free-electron gas.
(American Physical Society, 2000-12)
The energy loss of a heavy bare projectile with charge ZP moving in a free-electron gas is studied within the framework of the binary collisional formalism. The transition-matrix element is expanded in a perturbative series, ...
