Ok, I messed up in my problem. I have my problem worked down to this: (I have to make E = Capital sigma (summation) because the LaTeX isn't working for some reason.) E<i|h|j>[<r|i><a|j> - <r|j><a|i>] (Sigma is summed over ij, I just don't know how to make it show on here) Now is it...

Ok, now, is it possible for <r|i><a|j> = <r|h|a> ?

Yes sorry, that was a typo on my part. That first j was supposed to be an i.

Ok, here is my question. When you have < r | i >, this equals Sri. So logically if that is that case, if you had SriSaj this would equal < r | j >< a | j >, right? If so, then what does < r | j ><a | j > equal? I'm working a problem where I am trying to get a final answer of < r | h | a...

I'm not even sure if I am asking this the right way, but.. Does the Hartree approximation basically assume that electrons are independent and do not interact with each other? Also, do Exchange integrals essentially measure the interaction between two different electrons? Thanks.

I think I posted this question in the wrong part of these forums. I'm sorry about this.

I'm really struggling on even getting started on this problem. I have read the chapter several times now and I have tried to understand the explanations in the chapter. But I can't even get this problem started. All I ask is if anyone knows how to do this, can you just get me started or point...
