Abstract
By using bolometric detection of ESR we have observed that of order 1% of the two-body surface recombination energy of atomic hydrogen is de posited directly into liquid helium at the sample cell walls. Most of the energy is transferred from the recombination site by highly excite d H-2 molecules which are found to experience at least 150 wall collis ions in order to release half of their rovibrational energy.
