摘要：

We have used monoenergetic nozzle beams of para- and n-hydrogen to determine the adsorption dynamics in the so called 'precursor regime' on a (1 x 2) reconstructed Pt(110) surface. At low nozzle temperatures clear differences in the sticking coefficients of the two hydrogen modifications can be observed. An analysis of the data yields rotational state resolved sticking coefficients for the J = 0, 1 and 2 states. There is a pronounced decrease of the sticking coefficient with increasing J at constant translational energy.
