Two new surprises for three-body physics

" The idea that three atoms can form a loosely bound quantum state – even if any two of the atoms on their own cannot bind together – was first predicted by the Russian physicist Vitaly Efimov in the early 1970s. Now known as Efimov three-body bound states, they were first spotted in 2006 in a gas of caesium atoms that was cooled to just 10 nK by a team led by Hanns-Christoph Nägerl of Innsbruck University in Austria. Efimov states only occur for atoms that are bosons; that is, atoms that have integer, rather than half-integer, values of spin. "
