Efimov effect
From Wikipedia, the free encyclopedia
The Efimov effect is a solution to the quantum-mechanical three-body problem predicted by the Soviet theoretical physicist V. N. Efimov[1][2] in 1970, wherein three bosons can form a loosely bound system even if the two-particle attraction is too weak to allow two bosons to form a pair.
In 2006 scientists at Universität Innsbruck, Austria and at the University of Chicago in US reported[3] that they had detected Efimov states in scattering using caesium atoms at 10 nanokelvin.
