Observation of the Second Triatomic Resonance in Efimov’s Scenario
Observation of the Second Triatomic Resonance in Efimov’s Scenario
We report the observation of a three-body recombination resonance in an ultracold gas of cesium atoms at a very large negative value of the s-wave scattering length. The resonance is identified as the second triatomic Efimov resonance, which corresponds to the situation where the first excited Efimov state appears at …
