Absolute cross sections for electron-impact ionization of Cl{sup +} have been measured from threshold to 200 eV with the use of the crossed-beams technique. The cross section shows a peak value of 12.8{times}10{sup {minus}17} cm{sup 2} at about 70 eV. Results are compared to the semiempirical prediction formula of Lotz, with scaled cross sections for ions in the same isoelectronic sequence, and with other recent measurements. Expansion coefficients and formulas for generating ionization rate coefficients in the electron temperature range 10{sup 4}{le}{ital T}{le}10{sup 7} K are presented.
