    Unless implementation of this effect has recently taken place, it is likely
    neccessary to extract the neutron absorption locations within the active BF3
    volume from FLUKA and use typical energy-range relationship (Bethe-Block) to
    determine the amount energy that escapes the region of interest. I think you
    have two choices: interface your energy-range code inside MGDRAW or dump the
    locations to an external file and process the data seperately from FLUKA.
    And again assuming this has not been implemented, the Q value associated
    with the ground state Li7 state fission channel is not considered and should
    also be coded (Q~2.7MeV).

    Attached are old results using this approach... The difference in the two
    curves are caused by attempts to also include deadtime and pileup effects in
    the electronics. Anyhow, I do not presume to be an expert so perhaps others
    will have better ideas.
