I Nuclear g-factor

Looking at the Wikipedia page for the Lande g-factor, I'm a bit confused. I thought that [itex] g_I\approx5.585[/itex], that of the proton, but then there is the line saying that
This last approximation is justified because g_I is smaller than g_j by the ratio of the electron mass to the proton mass.

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

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.
