Study of low-energy electron attachment to 1,1,1-C2Cl3F3 using K(n d) Rydberg atoms

Studies of K(nd) Rydberg atom collisions (10≤n≤100) are used to investigate electron attachment to trichlorotrifluoroethane 1,1,1-C2Cl3F3 (TCTFE) at subthermal energies. The Rydberg atom data indicate that electron attachment to TCTFE occurs predominantly through dissociative capture and that the cross section for this process is large. Differences between the present results and those obtained using the threshold photoelectron spectroscopy (TPSA) technique are discussed.
