Ok. The Lande' g-factor is given as(adsbygoogle = window.adsbygoogle || []).push({});

[itex]g = g_L \frac{J(J+1)-S(S+1)+L(L+1)}{2J(J+1)} + g_s\frac{J(J+1)+S(S+1)-L(L+1)}{2J(J+1)}[/itex]

Most sources say that [itex]g_L = 1[/itex] exactly, but Bethe and Salpeter p214 seems to indicate that there should be a correction for reduced mass. [itex]g_L = 1- \frac{m_e}{m_i}[/itex]

Is that right? I think so, but I wanted to make sure, since nowhere else do I see it.

I assume g_s doesn't need any correction for reduced mass, since it's just the electron acting alone. Is that right?
