# Table of matrix elements of powers of r for radial functions in H atom

Im looking for some references here. I hope it is the right place to ask.

I need to find a table of (or a formula from which to extrapolate) the matrix elements of the radial functions of the hydrogen atom evaluated in powers of $r$ for both diagonal and off-diagonal elements. That is, I need this guys:

$<R_{nl}|r^k|R_{n'l'}>$

I found this article http://iopscience.iop.org/0953-4075/28/3/007 which is great, but Im looking for something more textbook-like, say suited for undergrad. I especially need positive powers until k=4.

Any help is very appreciated.

I do not think such a table exists. You can probably just hack the integral into Mathematica and retrieve the results. –  Neuneck May 14 '13 at 12:40
That's what im doing now, thanks –  user24273 May 15 '13 at 14:22
