Hi there=2C=20
I am a PhD student at Sciences faculty of Casablanca University 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.
=20
 I am interested to use geant4 to simulate neutron diffraction using a geom=
etry semilar to the real diffractometer .
 I am trying to simulate a material filter Al2O3 ( sapphire ) using fast ne=
utrons as the beam with an energy of 2 MeV=2C
=20
My problem is when I try to get an energy deposite for neutron=2C it actual=
ly works fine for other particles (e- =2Cgamma=2C..).
Please do you have 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 informations if n=
eeded.            =20
