Efimov states in Cesium
Check out the article in this month's Physics Today (April 2006, p. 19) on experimental observation of Efimov states in Cesium by Rudolf Grimm and others at Innsbruck. In order to clearly observe the states, they had to reduce the temperature to 10 nK.
The article reviews some theoretical studies also. Interestingly, it seems there are two predicted Efimov resonances in Cs, one of which is masked by breakdown of the scattering length approximation.
A nice summary of the Efimov results is here...
