(Phys.org)—Two teams of researchers working independently of one another and using wildly different approaches have confirmed nickel-78 to be doubly magic. In the first effort, an international team led by Louis Olivier ...
For the first time scientists have measured the radius of a calcium nucleus with 32 neutrons – indicating that nuclear physics theories don't describe atomic nuclei as well as previously thought.

The stability of an atomic nucleus strongly depends on the number of protons and neutrons it contains. Some nuclei can, in principle, live forever, whereas others last only a fraction of a second before decaying into different ...

The stability of atoms can vary considerably from one element to the next, and also between isotopes of the same element (whose nuclei contain the same number of protons but different numbers of neutrons). While many isotopes ...
