2020 is the 50^th anniversary of Physical Review C which was spun-off by its parent publication, The Physical Review, in 1970. As part of its anniversary PRC is creating a collection of milestone papers that "remain central to developments in the field of nuclear physics. These papers announce major discoveries or open up new avenues of research." 

PRC has selected a paper by Donal Day and his co-authors, M. Strikman, L. Frankfurt and  M. Sargsian, "Evidence for short-range correlations from high Q² (e,e’) reactions", published in Phys. Rev. C 48, 2451 (1993)  for recognition. This paper presented the first experimental evidence for the existence of short range correlations between nucleons in the nucleus. These short range correlations emerge due to the repulsive core of the NN potential  and generate very large momentum components in the nuclear ground state. Since the publication of this paper in 1993 there has been an explosion of activity, theoretical and experimental, associated with the study of short range correlations and these studies remain a significant part of Jefferson Lab's program.
