A criterion for an effective discretization of a continuous Schrödinger spectrum using a pseudostate basis
Tom Kirchner, Marko Horbatsch
We consider a Hamiltonian with a (partially) continuous spectrum and examine the zero-overlap condition which involves the projection onto exact continuum eigenstates of a…

A generalized independent atom model approach for net ionization of molecules by multiply-charged heavy-ion impact
Hans Jürgen Lüdde, Hans Jürgen Lüdde, Marko Horbatsch +1
The previously applied independent atom model (IAM) for highly charged ion-molecule collisions which implemented the suppression of multiple ionization and capture on the basis of…

The Independent Atom Model -- Pixel Counting Method for Ion-Molecule Collisions
Hans Juergen Luedde, Marko Horbatsch, Tom Kirchner
The independent atom model - pixel counting method (IAM-PCM) for the description of ion-molecule collisions is reviewed. The method was introduced (in 2016) to improve on the simpl…
