Abstract

Multiple ionization cross-sections of argon (Ar-Arn+, with n = 7,8) by electron impact are measured for energies ranging from threshold up to 3000 eV. The data were obtained by a time-of-flight mass-to-charge spectrometric technique. A comparison with other experimental data and with semi-empirical calculations is presented. The integrated oscillator strength (M7+2) for the production of Ar7+ was determined.
