KSU professors Makis Petratos and Mina Katramatou have reached a significant milestone with the April 2022 publication, in the journal Physical Review Letters, of measurements of the interactions of highly energetic electrons with the deep internal structure of a pair of "mirror" nuclei. One of the mirror nuclei in question has one proton and two neutrons, while the other has two protons and one neutron (i.e., tritium and helium-3, respectively). The new measurements have unprecedented precision, and were carried out at the Thomas Jefferson National Accelerator Facility in Virginia, a laboratory of the US Department of Energy.
