Question

Question: Bearing in mind its limiting cases of 1 and 2 mentioned in section 8.8, how would you describe the significance of the Lande g-factor

Short answer

Answer

X-rays do not start at hydrogen or helium because all of the electrons are electrons.

Step-by-step solution

Definition of Lande g-factor

The Lande g-factor is defined as

$\mathit{g}\mathbf{ }\mathbf{=}\mathbf{ }\frac{\mathbf{3}\mathbf{j}\left(j+1\right)\mathbf{-}\mathbf{l}\left(l+1\right)\mathbf{+}\mathbf{s}\left(s+1\right)}{\mathbf{2}\mathbf{j}\left(j+1\right)}$ (1)

where Iis the orbital angular momentum quantum number, sis the spin quantum number, and jis the total angular momentum quantum number.

Explanation

We see from equation (1) that the Landefactor includes all of the quantum numbers coming from the angular momentum. With this relationship, thefactor appears in the expression for the magnetic moment, through which the electron interacts with the external magnetic field.

Therefore it combines all of the angular momentum quantum numbers
