Dear @John_McFee and dear All,
I was following this post on “Question in neutron Capture” Question in neutron capture (Gd155(n, gamma)Gd156) reaction and i want to do something similar.
I have a spectrum of neutron energy and i want to insert it to the Gd target in water but I have trouble implementing it in Geant4, as i am new to Geant4. Is there any example macro in Geant4 that i could try or could you send me your macro as an example please. I shall be really thankful to you.
Dear @CHAO , May be you could help me out here.
You need more than a macro. You need the program that will run the macro. I have modified the B4a example program to get (n,gamma) spectra for a simple source-target-embedding medium geometry. It includes a macro to generate a neutron beam and one to generate neutrons from a point source. I cannot upload the file because the forum does not accept archive files, so I will email it to you.
Thank you very much for your help. I really appreciate it. My email address is firstname.lastname@example.org
