I have a question concerning the ion-FLUKA test version..
In the below message you mentioned that
"A (still experimental) version with ion interactions from 100 MeV/n up to
1000 TeV/n is available for interested users."
Can I assume that this version will accept a primary single nucleon with
energies greater than 20TeV (however less than 1000TeV) ??
