The transfer of energy from beams of atomic and molecular hydrogen to various surfaces (H2O, Ne, Ar) at liquid helium temperatures and UHV conditions has been investigated by means of a microcalorimetric technique. Evidence is given of the recombination of atomic hydrogen on H2O and Ar surfaces. Seeding the surfaces with up to one monolayer of H2 is found to increase the energy transfer by an order of magnitude.
