Detection of Long-Lived Complexes in Ultracold Atom-Molecule Collisions

Matthew A. Nichols, Yi-Xiang Liu, Lingbang Zhu +3

We investigate collisional loss in an ultracold mixture of ${}^{40}$K${}^{87}$Rb molecules and ${}^{87}$Rb atoms, where chemical reactions between the two species are energetically forbi…
