Resonant Five-body Recombination in an Ultracold Gas of Bosonic Atoms
arXiv:1205.1921 · doi:10.1088/1367-2630/15/4/043040
Abstract
We combine theory and experiment to investigate five-body recombination in an ultracold gas of atomic cesium at negative scattering length. A refined theoretical model, in combination with extensive laboratory tunability of the interatomic interactions, enables the five-body resonant recombination rate to be calculated and measured. The position of the new observed recombination feature agrees with a recent theoretical prediction and supports the prediction of a family of universal cluster states at negative that are tied to an Efimov trimer.
