i am also a little bit disturbed by the fact that energy conservation is not fullfilled. here are few events that have been extracted from a run.* G4Track Information: Particle = neutron, Track ID = 1, Parent ID = 0 *********************************************************************************************************

i clearly don t understand what happens since i only invoke G4 processes
 ( elastic and inelastic ) normally well suited for low energy  neutrons physics.
thanks for an answer.
i have also as in message 584 level at 15.1 MeV.
what s that?
