Atomic Deuterium Adsorbed on the Surface of Liquid Helium
arXiv:cond-mat/0012072 · doi:10.1103/PhysRevA.64.022901
Abstract
We investigate deuterium atoms adsorbed on the surface of liquid helium in equilibrium with a vapor of atoms of the same species. These atoms are studied by a sensitive optical method based on spectroscopy at a wavelength of 122 nm, exciting the 1S-2P transition. We present a direct measurement of the adsorption energy of deuterium atoms on helium and show evidence for the existence of resonantly enhanced recombination of atoms residing on the surface to molecules.
