Question Simulating Anti-Protons 

Keywords: Anti-Protons
Forum: Physics List
Date: 24 May, 2004
From: Harald <hpaganetti@partners.org>

I'm trying to simulate anti-protons in the energy range < 200 MeV slowing down in water. I tried to use the QGSP_BIC physics list and the physics list given in the gammaraytelescope example. None of them gives realistic results. In fact, the probability for annihilation in flight is way too high. More than half of the anti-protons annihilate in flight. In reality, about 70% should annihilate at rest. Does anybody have a physics setup for antiprotons below 200 MeV?
