Abstract

We investigate the presence of Feshbach resonances in ultracold alkali-dialkali reactive collisions. A potential-energy surface of Na₃ in the lowest quartet state is constructed and used in quantum scattering calculations. An analysis of scattering features is performed through a systematic variation in the nonadditive three-body interaction potential. Our results should provide useful information for interpreting future atom-molecule collision experiments.
