What does dσ/dΩ represent in terms of particle scattering?

[ian2012]

What is physically meant by:

\frac{d \sigma}{d \Omega}

Where \sigma is the cross section and \Omega is solid angle.
I can't really picture it.

 

[kulmalukko]

Differential cross section \frac{d\sigma}{d\Omega} tells you what is the probability that a particle decay with a certain solid angle.

 

[Meir Achuz]

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