Hi all,
I am getting very different results from the same experiment on different geant4 versions.
On version 11.2.2, decaying 238U in pure oxygen would produce neon (alpha reacts with oxygen nuclei)
e.g.
Ne20: 108 Emean = 1.099 MeV ( 700.7 keV → 1.633 MeV) stable
On version 11.3, the same experiment yields no neon.
The example above was QGSP_BIC_HP_EMZ, but it seems to happen regardless of physics list.
What is causing the difference? Is this an error?
Thanks in advance.
