[Gate-users] Disable Processes

[Josh Knowland]

All - I am having trouble running a macro with Bremsstrahlung disabled. As a test, I made a simple lead cube set as a Y90 source and recorded hits in it. Below are the physics setups and hits results for each test case.

What is the correct way to remove processes from a physics list?
