First observation of coherence in a highly charged ion. (July 2015) - Tashenov, S
Synopsis: We report the first observation of correlated x rays emitted by a heavy highly charged ion such as hydrogenlike uranium in the process of radiative recombination. The angular correlations between these x rays for the first time revealed a coherence of the populated state in this ion. The results also indicate a strong contribution of the spin-orbit interaction in radiative recombination.
