【 摘 要 】

Synopsis We report a numerically exact quantum mechanical treatment of the K+KRb reaction and discuss both universal and statistical aspects of its reaction dynamics. It is shown that the total rate is universal in character - validating the use of universal models in other similar reactions. However, the rotational distribution is shown to be statistical in character - which we argue is due to the chaotic nature of the reaction complex.
