[Gate-users] Compton and the Rayleigh interactions within the phantom

[Hermann Fuchs]

Hi

have you tried adding the Rayleigh physics process?
Perhaps it was omitted in the example physics.mac

Cheers,
Hermann

So far I attached "PhantomSD" to the phantom and I could see small Compton scattering and none of Rayleigh scattering. I used the original physics.mac from the example CT folder.
