"Three-Body Dynamics of Fragmentation Processes in Simple Atomic Systems"

Dr. Michael Schulz
Missouri University of Science and Technology


Understanding Nature requires addressing two major topics: first, we have to understand the forces acting in Nature. It is well established that the fundamental forces are mediated by the exchange of a gauge boson, which means that this mediation is fundamentally a two-body process. This property directly leads to the second topic which must be addressed: the spatial and temporal development of systems containing more than two particles under the influence of these pairwise acting forces. It is well established that the Schrödinger equation is not analytically solvable for such systems even when the underlying forces are completely understood. This is known as the few-body problem (FBP). For two reasons atomic fragmentation processes are particularly suitable to study the FBP: a) the underlying force in atomic systems is essentially understood. b) For simple atomic systems the particle number is small enough to make kinematically complete experiments measuring the properties of each particle feasible. In this talk recent experiments on the most fundamental few-body system (p + H) will be presented. A thorough theoretical analysis of the experimental data led to a major advancement of our understanding of the fragmentation dynamics.
