Observation and Analysis of Resonant Coupling Between Near-Degenerate Levels of the 2 1Σg+ and 1 1 Πg States of Ultracold 85Rb2

R. Carollo, M. A. Bellos, D. Rahmlow +4

We report on the anomalously high line strength of a single rotational level in the ultracold photoassociation of two 85Rb atoms to form 85Rb2. The v' = 111, J' = 5 level belongs t…
