    Dear User,
    I am comparing results for Energy deposition in Fluka and Geant3 for
    thin layer of Silicon ( typically 400 micrometer ).
    I found out that Fluka results ( using USRBIN ) give systematically
    20% to 30% lower energy loss in Silicon that Geant3.
    I use the recommended algorithm for the energy loss calculation
    (apportioning track length algorithm ).
    May some specific settings have to be included in my input file
    in order to cope with thin layer.=20
    Any help is welcome !=20
                                      thanks in advance.=20
