Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.

I use software called GATE, which uses the GEANT4 physics for simulations.
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 in 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.
The list is taken from GATE and, in short, is a set of macros that specifies which G4 physics that will be included in a simulation. Since the list is quite straightforward I suspect that the physics processes parameters are pretty easily understod by the GEANT4 community.
