The reaction of association of H+ ions with molecular hydrogen was studied for hydrogen number densities in the range 1012-1014 cm-3. The radio frequency 22-pole ion trap cooled to the temperature 10-30 K was used in the experiments.
The presence of binary and ternary channel of association reaction was observed. Measured rate coefficient of the ternary channel is k3 = (3 +- 1)x10-29 cm6s-1, the rate coefficient of the binary channel is kr = (2 +- 1)x10-16 cm3s-1 at 11 K.
