I have a form factor that only depends on the momentum transfer

if i have a spherical symmetric distribution of charge, f only depends on the radius; r = |

Then integration over all solid angels yields:

(there should be a r^2 inside the integral ;))

I do not understand how this Sinus - thing plops up.. all i know is this:

I really need a hint how to go from the exponential function to this sinus thing. =/

**q**, this is symbolised by writing the form factor as F(B]q[/B]^2).if i have a spherical symmetric distribution of charge, f only depends on the radius; r = |
