John R. Sabin is Professor Emeritus of Physics at the University of Florida and Adjunct Professor at the University of Southern Denmark.
His main research interest is in the interaction between high energy radiation and matter, in particular the stopping power of materials. The characteristics of the deposition of energy in matter by swift, massive particles is of interest in areas ranging from design of inertial confinement fusion devices to radiation therapy. The understanding and prediction of the processes involved in such energy deposition provide the unifying theme of the research. The research program has three distinct but interrelated parts dealing with: • stopping in atoms and molecules, with especial emphasis on aggregation effects • stopping in ultra-thin (several atomic layers) films as models for imbedded layers, overlayers and interfaces and as intermediates between gas and solid targets • trajectory dependent stopping if swift ions under channeling conditions in bulk targets
