of experimental data

Based on the comparison with experimental data a critical review is made in
Part I on empirical cross-section formulas for electron-impact ionization
of atomic ions. Most extensively studied are the formulas proposed by Lotz and
by Golden and Sampson. Several conclusions are drawn about the validity of
those formulas. A new type of scaling factor is proposed to improve the formula
of Golden and Sampson. Part II presents a compilation of experimental data on
electron-impact ionization of atomic ions with Z (atomic number) less that 19.
All these experimental data available are shown in a graphical form with the
results of the empirical formulas of Lotz and of Golden and Sampson. Experimental
data were surveyed through the end of 1980 and the data on multiple ionization
have been omitted.
