    my guess is that you are missing the heavy fragments produced besides the
    residual nucleus. You identify the residual nucleus through the statement

           WRITE( 41.0, * ) NPHEAV, ICRES, IBRES, ERES, EKRES

    then you loop over the heavy secondaries created in the nuclear
    evaporation

           do 20 ip = 1, NPHEAV
                 WRITE( 41.0, *) ip, KHEAVY(ip), TKHEAV(ip), WHEAVY(ip)
      20 continue

    but, if kheavy(ip) > 6 (it is the case of 6Li, 7Li, 6He, ...), you
    do not record charge (icheav(KHEAVY(ip))) and mass number
    (ibheav(KHEAVY(ip))) of the fragment.

    Let me know if this is not the reason

    Cheers

    Francesco
