3. Attempt at Solution

Well, this is part of a much larger problem. I am trying to compute the dipole moment matrix elements for a Hydrogen 2P -> 1S transition, and it involves this integral. In particular, this is the "z-component" of the |2,1,0> -> |1,0,0> transition - I've already found the x- and y-components to be zero for this transition.

I've spent nearly an hour looking through online integral tables, and I've found nothing useful.Can anyone help? Thanks!
