I don't know. What interests me is that this research is using a low energy approach to learn something new about the nucleus. Nuclear experimental research has largely been guided by Ruthford-like investigations requiring ever increasing energies. The research paradigm has been that with more energy comes more knowledge. NMR is low energy as well but it is_applied_ nuclear science. I could be wrong but at this time NMR doesn't seem capable of revealing anything new about the nucleus.
