Charge transfer in collisions of the effectively-one-electron isocharged ions Si3+,C3+, andO3+with atomic hydrogen

Excitation and charge transfer in proton-hydrogen collisions

Excitation and charge transfer cross sections for collisions of protons with hydrogen are calculated by direct solution of the time-dependent Schrödinger equation on a three-dimensional Cartesian lattice. The 2s , 2p , 3s , 3p , and 3d excitation cross sections and the 1s , 2s , 2p , 3s , 3p , and 3d charge transfer cross sections from the 1s ground state at 10-, 40-, and 100-keV incident proto...

Two-Center Effect on Low-Energy Electron Emission in Collisions of 1-MeV/u Bare Ions with Atomic Hydrogen, Molecular Hydrogen, and Helium. I. Atomic Hydrogen

Electron capture by Ne 2 ¿ ions from atomic hydrogen

Using a merged-beam technique, the absolute, total electron-capture cross section has been measured for collisions of Ne ions with hydrogen ~deuterium! atoms at collision energies between 139 and 1490 eV/u. These data are compared to three other published measurements, two of which differ from one another by a factor greater than two. Early quantal rate coefficient calculations for Ne ions with...

Strong isotope effects on the charge transfer in slow collisions of He2+ with atomic hydrogen, deuterium, and tritium.

Probabilities and cross sections for charge transfer by He2+ impact on atomic hydrogen (H), deuterium (D), and tritium (T) at low collision energies are calculated. The results are obtained using an ab initio theory, which solves the time-dependent Schrödinger equation. For the H target, excellent agreement is achieved between the present and previous results. Differences by orders of magnitude...

The role of atomic collisions in kinetic electron emission from Al surfaces by slow ions

We measured energy distributions of electrons emitted in the interaction of slow Kr and Na with Al surfaces. The data allow to correlate emission intensities with spectral signatures of electron excitation processes. Our results indicate that electron promotion processes leading to the excitation of Al target atoms plays the dominating role in kinetic electron emission from Al surfaces by slow ...
