Contribution

It extends a previous atomic ionization model to molecules, specifically H₂, incorporating interference effects and validating against experimental data.

Findings

Good agreement with experimental data for electron and proton projectiles.

Interference effects due to the two-center structure are observed and analyzed.

The model effectively captures the fully differential cross sections.

Abstract

Fully differential cross sections are calculated for the ionization of H$_2$ by fast charged projectiles using a semiclassical model developed previously for the ionization of atoms. The method is tested in case of 4 keV electron and 6 MeV proton projectiles. The obtained results show good agreement with the available experimental data. Interference effects due to the two-center character of the target are also observed and analyzed.
