摘要：

The recoil momentum imparted on the residual ion by the emission of a fast photoelectron gives rise to internal excitations of the ion. Because of this recoil, the photoionization transition is not a vertical one. By varying the photon energy and/or orientation of the system one can systematically create nuclear wave packets with different initial locations and momenta in nuclear space and thus explore nonadiabatic effects. As an illustrative example we study the dynamics in the vicinity of a conical intersection of a Jahn-Teller system.
