Are they sure it was really 42?
Thanks for posting this.

“When measuring a nucleus with a certain “magic” number of neutrons—82—the magnetic field of the nucleus exhibited a drastic change, and the properties of these very complex nuclei appear to be governed by just one of the protons of the nucleus.”
I get the gist of the article, and see this as a major development in the effort to comprehend one of the fundamental forces. What does it mean to say that the properties of the nuclei are “governed” by just one of the protons? Governed in what way? (They were measuring phenonena, so I presume the governing was discerned as variations in the measured quantities of something.) Governed by any one of the protons in a group that adds up to 82, or a particular one in a particular geometric relation to the others? Do the measured quantities reach a critical level at 82?
Fun with neutrons - bump for later...
La-139 has 82 neutrons and it is the stable isotope of lanthanum; I wonder if they’ve found any odd magnetic features for it?
One proton to rule them all.

Niels Bohr was the fellow who figured out the energy levels of electrons in orbit around the nucleus of an atom. His son is the fellow who figured out the energy levels of the nucleus itself.
