Venue:  C109, New Science Building

Abstract:Rydberg states of two valence electron atoms offer possibilities beyond those available in single valence electron atoms. In particular, the possibility of laser excitation of the second electron introduces novel ways to trap and manipulate Rydberg atoms. The essential properties of doubly excited Rydberg atoms will be summarized, and laser excitation of the second electron will be described in detail, showing a promising route to a dipole trap for Rydberg atoms.
