Hello,

Default Geant4 may provide non-accurate result for such low energy ions. You need, at least, study what value of cut to apply. Ion fragmentation cross section should be zero, so one would expect that only processes of elastic scattering and ionisation define the range of an ion. I would suggest to study ion tracking using example code

$G4INSTALL/examples/extended/electromagnetic/TestEm8 or TestEm7

or your own application with

/tracking/verbose 2

This will allow to see simulation histories. Without understanding what kind of events are in the tail and in the main peak it is not possible to make any conclusion. You may also use visualisation.

Also note, that for this task result may depend on Geant4 release, which you do not identified in your post.
