MIT researchers discover “neutronic molecules” about study μeV-Deep Neutron Bound States in Nanocrystals

Study shows neutrons can bind to nanoscale atomic clusters known as quantum dots. Many thousands of nuclei in neutronic quantum dot are able to stabilize bound states, which have diffuse wavefunctions at tens of nanometers [billionths of a meter]. These neutronic bound states in a quantum dot are akin to Thomson’s plum pudding model of an atom, after his discovery of the electron.

The range of strong interactions is of order 10^-14 to 10^-15 meters and extremely short as compared to the 10 nanometer scale of nanocrystals. Another strange feature is that neutrons were found outside these quantum dots. Why not inside, if nuclear power is involved somehow? Contrary to what the popular article says, neutrons interact electromagnetically. They have no charge but have a magnetic moment related to the neutron's spin so that they interact with the magnetic fields. How is this option ruled out? Was it really excluded?
