[tex]\frac{d \sigma}{d \Omega}[/tex]

Where [tex]\sigma[/tex] is the cross section and [tex]\Omega[/tex] is solid angle.

I can't really picture it.

If you multiply [tex]d\sigma/d\Omega[/tex] by the incident flux (number of particles per unit area) and by a small solid angle [tex]\Delta\omega[/tex], that gives the number of particles scattered into that solid angle.
