I'm reading Basdevant/Dalibard on 'Stationary States of the Hydrogen Atom' in preparation for a final this week, and the "Probability distribution function" for finding an electron in a spherical shell of thickness dr in the ground state is given.
It's not derived, so I was wondering if anyone could explain how to find such a distribution function.
Momentum, for example. If I wanted to find the probabilty distribution function for momentum, how would I do that?
I think I've got the wavefunction for the ground state of Hydrogen:
(using the equation involving spherical harmonics, the radial equation, and n=1, l=0, m=0)
[tex]|100>=(1/a_{o})^{2/3}e^{-r/a_{o}}\sqrt{1/{4\pi}}[/tex]
Any insight would be very much appreciated!
EDIT:
Oh, to clarify, Basdevant lists this as the answer for the radial probability distribution function:
[tex]P(r)dr=|\psi_{1,0,0}(r)|^2(4\pi)r^2dr[/tex]
I just don't know how he got there!
