Abstract
We show that the population of the rotational degrees of freedom of gas mol ecules affects their adsorption probability also for a physisorbed state. T he effect, expected to be very general, is demonstrated for the case of eth ylene interaction with Ag(001), when the physisorption probability is suppr essed for molecules produced with a hot nozzle, characterized by a substant ially larger average rotational quantum number.
