Effects on adsorption—desorption processes during irradiation

1 Effects on adsorption—desorption processes during irradiation 

The initial rate of oxygen chemisorption was directly proportional to the quantity of A1203 catalyst and radiation intensity but was independent of oxygen pressure. Chemisorption stopped when 7-irradiation ceased. Radiation-enhanced chemisorption of hydrogen obeyed the expression 

Results contrasting markedly with the foregoing and showing net radiation-induced desorption rather than adsorption, have been obtained not only in containment vessels subject to intense beams of ionising radiations [ 1 ], but also with well-characterised single-crystal surfaces exposed to the radiations employed in modern surface spectroscopic techniques (cf. Table 1). The phenomenon of radiation-induced desorption from the walls of containment vessels has acquired new technological interest from the probability that plasma-induced desorption from the
