摘要：

Argon gas is frequently introduced in small amounts as an impurity in high temperature laboratory plasmas. Ionic densities in these plasmas are determined by a lot of processes, essentially ionization, radiative, dielectronic and three-body recombination and charge-exchange. Absolute electron impact ionization cross-sections have been measured for the neonlike Ar**8** plus in the energy range from below the threshold for the metastable state to 2500 ev. No contribution of metastable states is observed. The results are well reproduced by the distorted wave Born approximation.
