<p class="MsoNormal"><span lang="EN-US">I am trying to run an example of a proton beam on gadolinium/Boron within the spread out bragg peak region and a detector just outside of the region.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><br>
</span></p>
<p class="MsoNormal"><span lang="EN-US">The idea is to use the neutron fluence that the proton beam creates to reproduce a neutron-Gd/Boron reaction.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">From this process, characteristic photons and gamma-rays should be detected but, they are not being properly represented.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span lang="EN-US">I am using the QGSP_BERT_HP_EMV physics list and I’ve added /gate/physics/addAtomDeexcitation<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">In theory everything should work but, the correct spectrum is not being produced showing the resulting photons/gamma-rays in the spectrum.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span lang="EN-US">Does anyone have any experience with this?<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">Is there some catch that I am missing?<o:p></o:p></span></p>
