the differences of γ energy spectrum for identifying
some hydrocarbon materials. The attempt of making
use of random incident neutron energy instead of
mono energetic neutron energy has paved the way
to imitate the physical condition in computational
simulation. For the time being, we consider GEANT4
should be a good alternative and candidate
for PGNAA simulation.
