Cold three-body collisions in hydrogen-hydrogen-alkali atomic system

Abstract

We have studied hydrogen-hydrogen-alkali three-body systems in the adiabatic hyperspherical representation. For the spin-stretched case, there exists a single $X$H molecular state when $X$ is one of the bosonic alkali atoms: ${}^7$Li, ${}^{23}$Na, ${}^{39}$K, ${}^{87}$Rb and ${}^{133}$Cs. As a result, the {\em only} recombination process is the one that leads to formation of $X$H molecules, H+H+$X$$\to$$X$H+H, and such molecules will be stable against vibrational relaxation. We have calculated the collision rates for recombination and collision induced dissociation as well as the elastic cross-sections for H+$X$H collisions up to a temperature of 0.5 K, including the partial wave contributions from $J^{\Pi }$=$0^{+}$ to $5^{-}$. We have also found that there is just one three-body bound state for such systems for $J^{\Pi }$=$0^{+}$ and no bound states for higher angular momenta.
