Efimov State
From Wikipedia, the free encyclopedia
Efimov State is a quantum mechanical stable bound state of three particles, with any two particle subsystem is unstable. This unusual state has infinite number of energy levels. It was proposed by Vitaly Efimov in 1970 theoretically[1]. In 2006, a group of experimental physicists claimed to observe such a state in ultracold gas of caesium atoms[2].
