# I Nuclear g-factor

Looking at the Wikipedia page for the Lande g-factor, I'm a bit confused. I thought that $g_I\approx5.585$, that of the proton, but then there is the line saying that
https://en.wikipedia.org/wiki/Landé_g-factor

It makes sense that the nuclear and Bohr magnetons would differ by the mass ratio, but I thought $g_s \approx 2$, $g_L=1$, and $g_I\approx5.585$. Then the additional factors in the Lande calculation would account for the different $J,S,F$.

I believe that the Wiki page is discussing atoms rather than nucleii.

You're right. I was confusing the nuclear g-factor of a proton with the nuclear g-factor of an atom.
