Energy deposited greater that incident energy for neutron?

Dear Fluka experts,

Summing up all energy deposited by a incident neutron of 600 MeV inside a
cube of 3*3*3 m made of pure
Plastic Scintillator (BC408) , i get counts in the final E_deposit/E_initial
spectrum greater than 1. .
I would like to understand how can it be that FLUKA gives in some cases
E_deposited > E_initial (neutron).
Could this be linked to wrong Energy threshold defintion for secondary
particles,
wrong physic model ( i used CALORIMETRY and DELTARAYS card ). I have seen
many reports using FLUKA showing
the same problem with incident neutron particle. It seems to be a known
problem but i can not figure out why ?

I will be very thankful for any explanation here.

Best regards,

Denis Bertini
