Hi
According top Hunds rule I have a ^{3}P term which should be the term for the ground state for a 2p^{2} shell (in this case the outer sub-shell), this means that I have a triplet state and thus a symmetric wave function for the spinn. Since the electrons are femions the total wave function...
Hi.
Suppose that you want to fint the wave function for ionized iron which have the electron configuration 1s2 2s2 2p6 3s2 3p6 3d6
And suppose that the LS-coupling scheme gives accuret enouhgt description och the energy levels.
Paulis exclusion principle and Hunds rule gives then that the...
Why do you only take in acount for the antisymmetric states?
Can someone give an exampel on how a antisymmteric states looks like for, 2 electrons and 3 electrons?
Thank you, Joqe
Hi again criz.corral!
Thank you so much, I think you had a terrific answer and everything is sorted out in a sens. Still somethings to consider but I'm very pleased with your answer.
Thank you again.

Hi criz.corral! Thank you for your kind answer.
Yes the particles are indeed identical and have spin 1/2.
As for the perturbation, a friend of mine suggested that I should ues degenerat perturbation theory, which I'm not familliar with and I don't see why I cannot use that you have...
If we have 2 particles in ground state in an infinite quantum well of length L (one-dimetion). Suppose then that the unperturbed energy is two times the ground energy of only one particle in an infinite qunatum well of length L.
Then I want to use first order perturbation theory to find the...
