Abstract
A radiotracer counting system was developed for adsorption and catalysis studies in ultrahigh vacuum using small area, single crystal surfaces. The counting system utilizes a rugged, compact, and rotatable surface barrier detector with a sensitivity sufficient to detect about 1×1013 molecules cm−2 containing carbon‐14. The operating characteristics and performance of this counting system are discussed along with its application to studies of 14C‐benzene chemisorption and rehydrogenation on the (111) crystal face of platinum.Keywords
