Neutron excess is the difference between the number of neutrons in an atomic
nucleus, its neutron number, and the number of protons in that nucleus. The
neutron number is determined by subtracting the atomic number from the mass
number ...

A magic neutron number N or a half-filled nuclear neutron shell (a neutron
number N of 1, 4, 10, 14, etc.) or an even number of neutrons confers added
stability to the isotope, which translates into greater stability than isotopes lacking
those ...
