Cross sections measurements for dissociation of CHClF2 by electron impact

CFC compounds at the atmosphere play a crucial role to the environment, being the main responsible for the increase of the ozone hole. Recent studies show that electron impact is the most likely process for the dissociation of these molecules, creating atomic chlorine, which breaks down ozone molecules. An experimental setup was built in order to analyse the collisional processes of CHClF2 (one of the CFC compounds still in use by the industry) by electron impact. Total and partial cross sections have been obtained, showing the predominance of the channel of chlorine atom production.
