Re: Electron radius-quantum
Expected value of the electron radius in what? Looking at your answer, I'm guessing it will be the hydrogen atom. If so, ANY book on QM will have the solution to this. Griffiths is a good introductory one. Hell, Wikipedia will have the form of the radial wave function. It's Bessel functions of some flavor, I think, though I can't remember how angular momentum comes in, and you'll probably want to look up the integral anyway.
