i'm physics student until 18 years ago and i don't finish the course.
this year i have some time and i decided to try finish.
one of the disciplines is Complements of Atomic Physics.
i understand the principles but the mathematical is very complicated for me.
it just have passed very years.
i just have three disciplines to finish the course.
if you can help me with this i apreciate.

Incidentally some of the ppl here don't have the book, but perhaps might be willing to help you. So how about doing all of us a favor and post both the texts of the problems and your attempts to solving them.

Exercise 2.16 A different procedure for deriving the above matrix ele...
ments uses the theorem that <K|H|L> = (N!)1/2<KHP|H|L> where |KHP >
is the Hartree product corresponding to the determinant |K>, i.e.,
|K> = |Xm(x 1 )Xn(X 2 ) . · . >

and

|KHP> = Xm(x 1 )Xn(X 2 ) . . .
Prove this theorem. Use it to derive the matrix elements of a sum of one-
electron operators.

You still need to show us some work. We are not going to do the problems for you.

as i said i'm with very difculty with mathematics because a don't study a long time ago 18 years. and i only read the book because i don't have so much time to do all that things.
but that's ok i understand your point of view.
