[Gate-users] Alpha particle physics

[Jenny Nilsson]

Dear Gate users,

I've been running a simulation with an alpha surface source. The simulation runs smoothly, no errors or warnings and the results seem reasonable

Still, I have a limited experience simulating alpha particles and want to make sure that I use the correct physics list.

I would greatly appreciate if someone with experience of simulating alpha particles could look at the physics list below and see if something is missing.

Best regards
Jenny Nilsson
