    Hello Alfredo,

    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) ??
