Abstract
This paper reports a study of Xe (nf) destruction in collisions with 1,1,1‐C2Cl3F3 and C5F8. The primary Rydberg atom destruction process is collisional ionization that results in the formation of a positive and a negative ion. Rate constants for this reaction have been measured for Xe (nf) over the range 26 ≤n≤43, and the major negative ion products identified. Cross sections for Rydberg electron attachment derived from these and earlier measurements are in good agreement with recent free electron attachment cross sections obtained using swarm techniques. This agreement further confirms that the study of Rydberg atom collisions can provide information on very‐low‐energy electron interactions.
