摘要：

The role of adsorbates deposited on sample and grid has been investigated with respect to the spontaneous desorption of negative sample specific ions. For this purpose experiments have been carried out in a UHV chamber. Both sample and grid could be cleaned by sputtering with Ar ions. The experiments allow conclusions to be drawn concerning the various processes involved in spontaneous desorption. These processes are discussed.
