Abstract
The general significance of adiabatic motion on quasi-energy surfaces for microwave ionisation of excited hydrogen atoms is investigated. It is shown that non-monotonic structures in the ionisation signal can be traced to near-degeneracies of coarse-grained quasi-energy surfaces of a few effective states. Further experimental implications are discussed.Keywords
