✦ Synopsis

The interaction of a single Rydberg atom with a single mode of the electromagnetic field and the resonance fluorescence of a single atomic ion stored in a radio-frequency trap were investigated. In the former experiment, the quantum collapse and revival of the atomic inversion predicted by the Jaynes-Cummings model could be demonstrated for the first time. In the latter experiment, antibunching and sub-Poissonian photon statistics were detected in the fluorescent light. Furthermore the observation of the crystallization of few ions in a trap is described. Since the stored ions can be cooled by the laser light and heated by the radio frequency field of the trap, subsequent phase transitions could be observed.

The nascent rotational and fine-structure state distributions in OH (o = 0) produced in the endothermic reaction H + CO2 OH + CO have been measured with hot hydrogen atoms from the photodissociation of HBr at 193 nm. Considerable OH rotational excitation broadly peaked at around K = 11 is observed.
