The universal behavior of a three-boson system close to the unitary limit is encoded in a simple dependence of many observables in terms of few parameters. For example the product of the three-body parameter ? and the two-body scattering length a, ?a depends on the angle ? defined by E3/E2 = tan2 ? . A similar dependence is observed in the ratio aAD/a with aAD the boson-dimer scattering length. We use a two-parameter potential to determine this simple behavior and, as an application, to compute aAD for the case of three 4He atoms. | |
