Dear Doris, > We are simulating background processes for a gas chamber. For us > the neutron background is very important, but the default interaction > rate is too low.

Have a look at the generic biasing examples (examples/extended/biasing/GB01 and GB02). > And there is another question.

Do you want to have different physics lists (i.e. processes) by particle type, or by volume? The former case is trivial -- a physics list is just a collection of process-particle associations. Can you please give more details about what you are trying to achieve here? Regards, Davide
