Abstract
Results of experiments on photodesorption of molecular nitrogen from the glass surface are presented. The study is performed in vacuum glass cells whose internal surface is illuminated by a powerful pulsed lamp. The dynamics of the nitrogen density in the cell due to photodesorption is studied with the use of a mass spectrometer and a vacuum ionization lamp. A qualitative comparison of experimental data with results predicted by a developed theoretical model is performed.
