Analytical evaluation of r^l integral

[squareroot]

Hello,

I need to find the matrix elements of

in the particular case where l = 1. This should have an analytical solution but I have no idea where to start with this demonstration.

Any suggestions on where to start digging?Ty!

Start defining your notation! What's $R_{nl}$? What's the domain of integration? Last but not least, homework problems should be sent to the homework forum!

My guess is that $R_{nl}$ is the radial part of the electronic wave function for the hydrogen atom.

This indeed looks like homework, and I will therefore close the thread and ask you to start another one in the homework forum, with a proper description of the problem and an attempt at a solution. If my judgement is wrong, please PM me.
