Efimov Molecule (IMAGE) University of Chicago Caption This illustration shows the sizes of triatomic molecules that follow the geometrical scaling predicted by Vitaly Efimov in 1970. University of Chicago physicists have reported evidence of this geometric scaling in three-atom, lithium-ceisum Efimov molecules at a temperature 200 nanokelvin, a fraction of a degree above absolute zero (minus 459.6 degrees Fahreneheit).
