Stuart Elston

Department of Physics & Astronomy
Tennessee State University
United States of America


Professor Stuart B. Elston received the B.S. degree in Physics from Rochester Institute of Technology in 1968 and, following two years of service in the United States Marine Corps, earned a Ph.D. in Physics from the University of Massachusetts at Amherst in 1975. After two years as a Postdoctoral Research Associate and two years as Research Assistant Professor, he joined the faculty at the University of Tennessee in 1979. He has also held a part-time position as Adjunct R and D Participant in the Physics Division at Oak Ridge National Laboratory from 1979 to 1996.

Research Interest

My research studies collisions of accelerator-produced projectile ions with atoms, molecules, bulk solids, and surfaces, emphasizing the observation and interpretation of electron emission produced during such collisions. Early work demonstrated that the energy and angular distribution of electron emission in the extreme forward direction, at speeds nearly matching that of the projectile ion - and corresponding to the emission of so-called 'convoy' electrons - provides a particularly sensitive probe of collision inter-actions capable of resolving different emission mechanisms such as target electron capture and projectile electron loss
