William Tireman (Physics) had a paper titled “Probing the Repulsive Core of the Nucleon-Nucleon Interaction via the 4He(e,e'pN) Triple-Coincidence Reaction” published in Physical Review Letters by the American Physical Society. The paper explained results of an experiment conducted in collaboration with scientists at Jefferson National Laboratory and 47 other institutions to measure the nucleon-nucleon interaction at the repulsive core limit on helium-4. The experiment was conducted in 2011 using the high-energy electron beam at Jefferson National Laboratory. Tireman’s involvement included constructing 18 plastic scintillation detectors with the help of NMU undergraduate students. He also assisted with experiment setup and data collection.
