Hi =2C
 I am a PhD student at Sciences faculty of
Casablanca University HassanII  Morocco and CNESTEN (National Center of the
Energy Sciences and Nuclear
 Technology).
 Please=2C is it possible
to help me I have a problem since more than three weeks without any
solution it would be really very helpful if
 you can help me to solve it.
I am ting to simulate neutron diffraction using geometry similar to the rea=
l diffractometer .
I
have trying  the same problem with these materials B4C =2CH2O=2CCH3=2CAl2O3
with geant4.9.2.P02 using neutrons (fast=2Cthermal) as the beam .
My problem is when I try to get an energy deposit for neutron =2C it actual=
ly works fine for other particles (e-=2Cgamma) .
< B4C is a good absorber of a thermal and I can't found the energy deposit =
for neutron >
Please have you  an idea what I am doing wrong in case of neutrons.
Many thanks.
Naima
PS: I am not sure if I am clear=2C I can send more information if I needed =
.           =20
