A search for Efimov states is carried out in terms of a one-dimensional model three-body problem. A numerically exact solution is obtained that allows scanning through the resonance condition. No evidence is found for the existence of an infinite number of such bound three-body states. It is deduced from one-dimensional results that such an infinity of bound states should also not arise in a complete three-dimensional calculation.

A model for finite-temperature effects on three-body recombination in Efimov systems is presented and used to determine the three-body parameter for fermionic lithium-6, which may serve as a basis for future measurements in different systems in a search for nonuniversality in Efimov physics in atomic systems.
