1. The problem statement, all variables and given/known data
I've been given a question using a spherically symmetric form of the form factor, but before I ask a specific question, I would like to get some more general advice and then try it on my own.
In my notes from lectures, the form factor is defined as:

F(q$$^{2}$$) = 4$$\pi$$ $$\int$$f(r) sin(|q|r/$$\hbar$$) / (|q| r $$\hbar$$) dr

But the question I've been given asks to find F(q). Is there some way to relate F(q) to F(q^2)?

Also, in the solution to this problem, my lecturer uses the following equation:

F(q) = 4(pi)/q $$\int$$$$\rho$$r sin (qr) dr

What happened to the hbar and the r in the denominator?

Is there a website where I can learn about this in more detail, or even a textbook? I have been using Introductory Nuclear Physics by Krane and it doesn't seem to have much on it.
