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. Joqe

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...
