Re: target recoil energies

Hi Ian,

no.
In FLUKA single coulomb scattering is performed on request just in order
to have a more detailed treatment of the particle trajectory deviations,
but has no relation with energy loss. The latter is calculated in the so
called condensed history approach not taking into account single Coulomb
interactions with electrons and nuclei but assuming a continuous loss
along the step, on the basis of the electronic+nuclear stopping power. By
the way, while trajectory deviations are dominated by interactions with
nuclei, the energy loss is dominated by interactions with electrons.

Kind regards

Francesco
