Description Vladimir.Ivantchenko 2022-06-22 13:26:15 CEST 
Michel Maire reported problem he observing for dEdx and range of 80 keV Rn222 ion in liquid argon. In fact, there are two problems: incorrect dEdx from nuclear stopping computed by G4EmCalculator and incorrect approximation of dEdx and ranges of ions below low-energy edge of ion stopping power data.

Please, assign this problem to me.

the problem is fixed and the fix will be available in the next public release 11.1, the problem was in G4EmCalculator when stopping powers for ions were computed.
