摘要：

The recombination rate for three identical bosons has been calculated to test the limits of its universal behavior. It has been obtained for several different collision energies and scattering lengths a up to 10(5) a.u., giving rates that vary over 15 orders of magnitude. We find that universal behavior is limited to the threshold region characterized by Eless than or similar toh(2)/2mu(12)a(2), where E is the total energy and mu(12) is the two-body reduced mass. The analytically predicted infinite series of resonance peaks and interference minima is truncated to no more than three of each for typical experimental parameters.
