Inaccuracies
It says here "In cases with odd numbers of either or both protons and neutrons, the nucleus often has nonzero spin..." Obviously, if the number of nucleons is odd, that means for odd-even or even-odd nuclei, the spin is definitely non-zero. Now I accept that in principle it would be possible that for an odd-odd nucleus the last proton and neutron compensate their spins, but at Even and odd atomic nuclei it says that at least among the primordial nuclei, this does not happen. Are there known artificial odd-odd nuclei with zero spin? Otherwise I would suggest to change the above expression to say "always" or at least to drop the "often".

And with respect to the section on g-factors: what is called g(s) here is what I think about if I read "g-factor". What is called g(l) here seems to be about the orbital contribution to a nucleus' spin (there is no definition of these quantities). Thus it is quite trivial that these are 0 and 1 for neutrons and protons, respectively, isn't it? I also wouldn't called these values "measured", it's just that experiments are in accordance with theory with respect to these values. In contrast, g(s) are clearly measured, as there is no theory that would predict these values. But in general, to me it seems that the article would become better if this distinction would not be made and only g(s) would be treated and called "g-factor", in accordance with general usage. Perhaps a note could be made that the orbital contribution is as expected, but the present presentation is unnecessarily complicated, I think. Seattle Jörg (talk) 09:30, 8 April 2022 (UTC)
