Structure and Dynamics of Excited Atoms.

Abstract

During the five year period of grant AFOSR-9O-0036 we have worked on two different kinds of projects, microwave multiphoton processes and resonant collisional energy transfer. Both kinds of experiments are carried out with highly excited, or Rydberg atoms, which allow us to do quantitative experiments giving insights which would be difficult or impossible to obtain in other systems. For example, our experiments on microwave multiphoton excitation and ionization have demonstrated that the Floquet, or dressed state, approach provides an accurate description of the evolution of atomic systems in intense radiation pulses. The understanding derived from our microwave experiments resolved a controversy about how laser multiphoton ionization through intermediate resonances occurred. In the two following sections of this report we describe the collision experiments and the microwave multiphoton experiments. jg p.4
