  We have measured absolute total cross section for LMM Auger electron emission
of Cl in chlorinated methane and benzene chloride in collision with H+ ion.
Projectile energy dependence of the total yield as well as the angular
distribution has been studied. Incident proton energy has been varied from 125
keV to 275 keV in steps of 50 keV. C KLL Auger yield have been compared with
previous studies and found to be in agreement within the effect of chemical
species It has been found that the LMM Auger yield of Cl is much more
significantly affected by molecular environment than the C KLL.
