The sticking of hydrogen atoms with kinetic energies in the range 0.003-10 eV on a clean (001) tungsten surface has been investigated using molecular dynamics simulations. The atoms are found to stick to the surface at 0 and 300 K, with a sticking coefficient smaller than 0.6 for kinetic energies higher than 3 meV. The adsorption sites for H on the W(001) surface are also presented. The dominant site is in perfect agreement with the experimentally found bridge site.
