Description joukov 2021-02-04 16:15:01 CET 
In simulations, antiD interaction  with material leads to occasional exceptions
(one out of 10k events)

Comment 2 Alberto.Ribon 2021-03-11 15:32:53 CET 
Thanks for the feedback, but I am unable to reproduce it, after running millions of anti_deuterons of 34.4954 GeV kinetic energy on G4_H target. I have tried also different versions of Geant4 (today's development, 10.7.p01, 10.6.p03).
So, I cannot fix anything.
