I thought that nuetron does not contribute to magnetic moment due to lack of charge, not spin. I did not know the formula for magnetic moment of nucleons. I guess that it may be somehow similar to the previous formulas, where the elementary charge of an electron apears. I suppose that it is...

Contribution of electrons to the magnetic moment of an atom is found. Now, have a look at the magnetic moment of nucleus. Proton has the spin magnetic moment u = g_S * (e *s) / (2*m_p), where g_S=1, e is charge, s=1/2 spin, and m_p is mass of proton. Nuetron does not contribute any magnetic...

I have noticed a mistake I made in the previous post when descibring the quantum numbers of V. They should be: 1) n=3 l=2 ml=0 s=1/2 2) n=3 l=2 ml=1 s=1/2 3) n=3 l=2 ml=-1 s=1/2 Therefore L=1+0-1=0 and S= 3 * 1/2 = 3/2 Following formulas you've provided J=S= 3/2 Now I should calculate g_J...

And for subshell excatly half-filled?

So why there is J=L-S instead of J=L+S=1+1/2=3/2? An the other question why it is assumed that electrons firstly have spin 1/2 and then -1/2. I mean that if we take the absolute value of total spin of electrons it does not matter on which 'side' (- or +) they really are. I guess that L is not...

I understand that the same situation is in case of 5B, where there is also only one electron on the last subshell 2p. Therefore Na and B has the same electronic contribution to magnetic moment. Let's leave now the calculation of magnetic moment of nucleus and take care of contribution of...

OK. Let's take a 23Na atom. Its electronic configuration is 1s²2s²2p⁶3s¹. We can omit talking about electrons from first and second shell as their total contribution to magnetic moment is 0. The only electron we consider now is that on the 3s...

So the maximum is Emax = const + 8t when the multiplication of cos functions gives -1 and Emin = const -8t as the multiplication of cos functions gives 1. It implies that W = 8t - (-8t) = 16t. Now I should find kx,ky and kz fow which that cos functions multiplications results in 1 and -1. I have...

According to tight binding moment, for BCC crystalographic structures (such as Fe), energy E depends on wave vector kx, ky, kz: E(x) = const - 8t cos(kx * a/2)*cos(ky * a/2)*cos(kz * a/2), where t>0 is the model parameter. What is the bandwidth W in terms of parameter t? Can you find kx, kz, and...

We can easily write down configuration of electrons in an atom of given element. The question is how can I calculate the magnetic moment of given atom knowing configuration of electrons in that atom? Or maybe some other data is needed? Especially I am interested in calculation of magnetic moment...
