The H2-Cs surface interaction potential is directly investigated by scattering a rotationally cold beam of HD molecules from a Cs surface (see angular distribution diagram). The probability of rotational excitation is two orders of magnitude smaller than for Cu and other metal surfaces. Coupled channel calculations interpret the results, and the anomalous behaviour is linked to the peculiarities of the closed-shell alkali surface interactions.
