Hi, when I try to simulate 2-to-4 decays from U238 or Th232 chain, I do not get the correct number of them. For example, if I shoot a U238 ion (/gun/ion 92 238 0 0) with different nucleus limit I get: U238 - Th234 (grdm/nucleusLimits 230 238 90 92) Th232 - Ra228 (grdm/nucleusLimits 228 232 88 90) Expect 2 decays, in the simulation 4. U238 - Pa234 (grdm/nucleusLimits 234 238 90 92) Th232 - Ac228 (grdm/nucleusLimits 228 232 89 90) Expect 3 decays, in the simulation 1. U238 - U234 (grdm/nucleusLimits 234 238 92 92) Th232 - Th228 (grdm/nucleusLimits 228 232 90 90) Expect 4 decays, in the simulation 1. If I simulate 1 decay, equal to 5 or more, I get what I expect, e.g.: U238 - Th230 (grdm/nucleusLimits 230 238 90 92) Th232 - Ra224 (grdm/nucleusLimits 224 232 88 90) Is it me or GEANT4 doing something wrong?
