We have studied hydrogen-hydrogen-alkali three-body systems in the adiabatic hyperspherical representation. For the spin-stretched case, there exists a single XH molecular state when X is one of the bosonic alkali atoms: {sup 7}Li, {sup 23}Na, {sup 39}K, {sup 87}Rb, or {sup 133}Cs. As a result, the only recombination process is the one that leads to formation of XH molecules, H+H+X{yields}XH+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+XH collisions up to a temperature of 0.5 K, including the partial wave contributions from J{sup {Pi}=}0{sup +} to 5{sup -}. We have also found that there is just one three-body bound state for such systems for J{sup {Pi}=}0{sup +} and no bound states for higher angular momenta.
