Excitation from 2s-level of hydrogen by heavy fast ions

The eikonal impulse theoretical method is used to study the hydrogen excitation from the 2s-metastable level by ion impact. Cross sections and density matrix elements are calculated for the excitation process: PZe + H(2s → n = 3). The calculated cross sections are about one order of magnitude larger...
