Weakly bound states of a molecular adsorption of hydrogen, with desorption temperatures ~ 5, 8, and 60 K, have been observed. Atomic adsorption states as well as molecular states are populated at 5 K. The formation of the molecular state with 8 К broadens the angular distribution of scattered molecules.
