By reconstructing a nearly forgotten 1938 experiment, scientists have uncovered new significance in an early observation of deuterium-tritium fusion that still shapes nuclear science today. (Artist’s concept). Credit: SciTechDaily.com Physicists confirm DT fusion insights from a 1938 experiment. The findings connect past theory with current fusion efforts. A team at Los Alamos National Laboratory has successfully recreated a significant yet largely overlooked physics experiment: the first recorded observation of deuterium-tritium (DT) fusion. Their updated version of the 1938 experiment, recently detailed in Physical Review C, reaffirms the pivotal role of University of Michigan physicist Arthur Ruhlig. Ruhlig’s original work likely...
