The process of three-body recombination, where two atoms form a molecule and a third atom carries away part of the released binding energy, is still hardly understood. In particular, the population distribution of molecular product states is a subject under discussion for lack of experimental data and since the theoretical description is difficult. Here we present first measurements of the product-state distribution of diatomic molecules after three-body recombination for the regime of lowest binding energies. From our spectra, we extract the dependence of the population distribution on the vibrational and rotational excitation, providing important information to test and develop model calculations.
