Electron-impact ionization of Li2 using a time-dependent close-coupling method

The time-dependent close-coupling method is applied to calculate the electron-impact ionization of a diatomic molecule with interior closed subshells. The ionization of the outer 2sσ subshell of Li2(1sσ 22pσ 22sσ 2) is carried out using a standard core orthogonalization method. At the peak of the Li2 cross section, the nonperturbative time-dependent close-coupling cross sections are found to be...

Time-dependent close-coupling calculations for the electron-impact ionization of carbon and neon

A time-dependent close-coupling method is used to calculate the electron-impact ionization cross section for the outer 2p subshell of both carbon and neon atoms. The inner 1s and 2s subshells are treated using pseudopotentials, while interaction with the remaining 2p core electrons is handled in a configuration-average approximation. When the time-dependent ionization cross section for the 2p s...

Single and double ionization in C6+ + He collisions

Singleand double-ionization processes in C6+ collisions with the He atom at an incident energy of 100 MeV/amu are studied by direct solution of the time-dependent Schrödinger equation. A time-dependent close-coupling method based on an expansion of a one-electron three-dimensional wave function in the field of He+ is used to calculate single-ionization cross sections. A time-dependent close-cou...

Time-dependent close-coupling calculations of the triple-differential cross section for electron-impact ionization of hydrogen

The formulation of the time-dependent close-coupling method is extended to allow the calculation of electron-impact triple-differential cross sections for atoms. The fully quantal method is applied to the electronimpact ionization of hydrogen at an incident energy of 54.4 eV for various scattering geometries. The timedependent close-coupling results are found to be in very good agreement with t...

T-matrix calculations for the electron-impact ionization of hydrogen in the Temkin-Poet model

An eigenchannel R-matrix expansion of the T matrix is used to calculate total integrated and ejected energy differential cross sections for the electron-impact ionization of hydrogen in the Temkin-Poet model. In previous close-coupling results, unphysical oscillations in the total ionization cross section could be averaged over due to the smooth dependence of the cross section on the incident e...
