[Olympus] some definitions

[Belostotski, Stanislav]

Dear colleagues ,I suggest to include the following definitions in the 
section GENERAL or MC section:

1. Bremsstrahlung: ep interaction with e ,p and a real photon  in the 
final state. As a second order correction to the SPE amplitude, the 
bremsstrahlung photon may be produced by the initial or final lepton, or 
by  the initial or final proton.
2.Inelastic ep scattering: the ep interaction with a pion(s) in the 
final state.
3. Radiative effects in material budget: those resulting in the energy 
loss of   scattered lepton due to interactions with spectrometer 
materials, e.g., e+e- pair production or e+ annihilation  in the target 
cell wall, target chamber exit window,air  etc.

Any comments, suggestion?
