Abstract
A theory for photodesorption of chemisorbed species is developed. Two cross sections are computed-one for photodesorption in the excited state with subsequent free atomic fluorescence and the other, the total desorption cross section in any state. A decay mechanism involving surface plasmon and particle-hole pair excitations is introduced to account for nonradiative deexcitation processes. A comparison is made to other mechanisms such as photoelectron-stimulated desorption. Estimates show that the cross section is of sufficient magnitude to be readily detected in the laboratory.
