ABSTRACT
The study of Ultra Violet (UV)–emission in ion–molecule collisions has been the subject of numerous investigations over the last forty years. An important role in this field of research has been played by the works of Pretzer et al. and of Andreev et al. For a long time cross sections for Lyman–alpha excitation and emission obtained in these works were used as an absolute basis for the calibration of the UV–detection systems. All the data were taken from original sources. Only in a small number of cases were secondary data sources used. Much of the data taken from journals and published proceedings of conferences were presented only in graphical form. The most important stage of obtaining the recommended cross sections is critical assessment of the accuracy of the original experimental data. The tables are supplemented with the values of fitting parameters and with an indication of data accuracy and validity range of fitting expression.
