Complex structure of resonant coherent excitation peaks for heavy relativistic hydrogen-like ions under planar channeling

Abstract

The computer model for the resonant coherent excitation of heavy relativistic ions under planar channeling in crystals taking into account the fine structure of the energy levels of the orbital electron and the ion ionization from both the ground and first excited state is presented. The model has been used to explain the experiments carried out under planar channeling of 390 MeV/n 17+Ar ions. Reasonably good agreement for the calculated and experimental data has been obtained.
