Hi Dimitrios, thank you for writing back. Dd your simulation take longer with manually defined processes instead of physics list?<br>

<br>
I also tried to disable a process after loading a PhysicsList and I<br>
couldn't manage to do it.<br>
A way to remove a process is to define manually the processes you want.<br>
A typical physics list for EM processes is the file physicslist_EM_std.mac<br>
in benchmarks of GATE installation folder (Rayleigh scattering is missing)<br>
but there are more details in usersguide.<br>
I tried it and it worked.<br>
