Abstract
The model used in the first part of this investigation is enlarged to take account of the experimentally found inhibition of desorption by gases from the rest-gas atmosphere of the target chamber. The main parameters that can be found by adaptation of a model set of equations are the rate ratios for transfer of chemisorbed atoms in the surface and back, and of the maximal desorption current densities from the surface into the vacuum for deuterium and foreign gases. The desorption cross sections are discussed in relation to the electronic stopping power of the fast ions.
