An in-situ RBS system for measuring nuclides adsorbed at the liquid-solid interface

An in-situ RBS system has been developed in which heavier nuclides adsorbed at the inner surface of a thin lighter window specimen of liquid container in order to determine the rate constants for their sorption and release at the interface. The testing of a thin silicon window of the sample assembly, in which Xe gas of one atmosphere was enclosed, against the bombardment of the probing ion beam has been performed. A desorption behavior of a lead layer adsorbed at the SiO2 layer of silicon window surface into deionized water has been measured as a preliminary experiment. (author)
