AbstractIn this work plasma parameters of the constricted argon discharge have been determined by an iterative method. For the conditions 20 ⩽Rp⩽ 300 cm Torr and 0,05 ⩽i/R⩽ 2,5 A/cm the electron density, the electron temperature, and the gas temperature are obtained. These results are compared with measurements and calculated values of other authors. With the exception of the determination of gas temperatures at 2,5 A/cm the agreement between our results and the measurements of some other authors is satis
