TL;DR: A 7 Li + -ion beam was overlapped with resonant copropagating and counter- propagating laser beams and a strongly enhanced narrow peak appeared in the Schottky noise spectrum in addition to the uncooled ion distribution.

TL;DR: The first observation of laser-induced recombination, performed with merged beams of protons, electrons, and laser photons in an ion storage ring, is reported and could be well described by a simple extension of the field-free quantum-mechanical theory.

TL;DR: Determination des energies et sections efficaces pour plusieurs etats de la configuration 2l2l' (avec n≥3) pour 90% de la section efficace totale.

TL;DR: The Heidelberg heavy ion test storage ring TSR started operation in May 1988 and the first experiments were performed in 1989 as mentioned in this paper, where the lifetime of the ion beams observed in the first experiment can be explained by interactions with the residual gas.

TL;DR: The electron cooling device of the Heidelberg cooler storage ring has come into operation and for the first time has cooled ions heavier than protons as mentioned in this paper, and it has proven that the cooling force is increasing with the charge of the ion.
