This value is in excellent agreement with the theoretical value of 0.100. The average energy of the L peak was found to be 273 plus or minus 6 ev. When a new value of 265 plus or minus 5 ev is obtained for the critical L absorption energy of chlorine by interpolation and the effect of the Auger process is considered, it is concluded that the energy to produce an ion pair in argon at 0.2 kev is 0.98 plus or minus 0.04 times the value at 2.8 kev.
