About $10 cm^{-1}$ below the limit the level density is so high that even for narrowband excitation $(\Delta\nu_{laser} = 300MHz)$ about 150 n-states are coherently excited. Experimentally, signal recurrences were observed as a function of delay of the field ionization pulse, that match the splittings between Stark states. A theoretical interpretation of the phenomena is presented fully based on the analysis of Rydberg states in the hydrogen atom, in which the electron is replaced by the heavier $H^{-}$ particle. en_US dc.format.extent 159667 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title OBSERVATION OF COHERENT WAVE PACKETS IN THE $H^{+}H^{-}$ ION-PAIR POTENTIAL. en_US dc.type article en_US
