Electron-atom collision cross sections in argon: an analysis and comments

Experimental data on electron-atom collision cross sections in argon published during the period 1980-2002 are compiled and reviewed, with 123 references. Total, integral elastic, differential, excitation and ionization cross sections in the energy range 0-1000 eV are considered separately. A comparison between various measurements and, between various semi-empirical formulas are given. Improved formulas previously unpublished are also given where required. The sigma rule (the total cross section is the sum of partial cross sections) holds good in argon to an accuracy of /spl plusmn/5% in the energy range 12-1000 eV. A recommended set is provided.
