argon gases was studied for energies in the range of a few to 250 kev. A large cylindrical ionization chamber was used for this study. The chamber was alternately operated as a proportional counter and an ionization chamber to measure the rate with which the protons entered the chamber and the total ionization produced by them, respeetively. The results indicated a straight-line relation between the ionization yield and proton energy for energies above 75 kev in nitrogen and above 25 kev in argon. Straight-line plots of the data had slopes corresponding to 36.6 plus or minus 0.7 ev per ion pair for nitrogen and 26.5 plus or minus 0.5 ev per ion pair for argon. For argon the straight-line plot intercepted the energy axis at 1.4 plus or minus 0.9 kev, indicating a slight ionization defect. (auth)
