Abstract

The theory of resonant coherent excitation of relativistic hydrogen-like heavy ions under planar channelling in a crystal is developed, which takes into account the fine structure of electronic energy levels of an ion, the Stark effect due to continuous planar potential, and ionization both from ground and excited states during ion penetration through a crystal. The theory is applied to explain the experimental data on resonant coherent excitation of 390 MeV/u Ar17+ ions under (2 2 0) Si planar channelling, and reasonably good agreement of calculations and experimental data is achieved.
