I am measuring the radiation spectrum from neutron capture in gadolinium. In the experimental data i can see the proper gamma ray peak at 79 keV, the proper conversion electron peaks at 72 keV, and a peak at 43 keV which i attribute to the k-alpha x-ray from Gadolinium.
I am using Geant4 to simulate the experiment. I am using the QGSP_BERT_HP physics list along with G4RAdioactiveDecayPhysics class. This properly reproduces both the gamma rays and conversion electrons. However, I see no indication of the k-alpha x-ray at 43 keV. Is there something i need to "turn on" in the physics list to account for this?
Any advice is appreciate. Sincerely, matthew allen
