Abstract :
We have measured experimentally the mobilities of Ar ions in Ar at different pressures (1, 1/2, 1/4, 1/8 and 1/16 atm) and for low reduced electric fields (E/N < 10 Td). The results are in good agreement with those available in the scientific literature and they indicate that Ar2 + is the dominant ion species. The variation of the mobility with the pressure reveals the presence of the Ar3 + ions. Space charge and impurity effects were accounted.
