✦ Synopsis

We obtain a large number of eigenenergies for bound states of an electron in the wake potential of a fast highly charged ion traversing a solid. The set of semiclassical eigenenergies pertains to eigenstates lokrlized in the regular part of the classical phase space where RAM tori exist. By comparing with a full quanta1 calculation using diagoualization oflarge Hamiltonian matrices we can directly associate individual quantum states with the classically regular and chaotic portions of the phase space.

In this work we studied the collinear F(\*P,$ + Hz system in a strong CO2 laser field. It was found that the tiajecror) surface hopping method (TSHM) yields entirely different results than the exact quantum-mechanical treatment. A curvecrossing model was devised to esplain the discrepancy.
