<p class="MsoNormal"><span lang="EN-US">I have been running many simulations with varied setups trying to reproduce a Gadolinium neutron capture therapy reaction in GATE but, I am unable to observe the capture reaction taking place.<o:p></o:p></span></p>

<p class="MsoNormal"><i><span lang="EN-US">I have been working on a simple setup of an isotropic thermal neutron source surrounded by a thin spherical sheet of Gd. I have created a large detector volume surrounding the entire setup with the Energy Spectrum
Actor on the Detector. The results are that no thermal n’s are being captured by the Gd. The thermal n cross section for Gd is extremely large.<o:p></o:p></span></i></p>
<p class="MsoNormal"><span lang="EN-US">I suspect there is some kind of catch, like only a specific physics list can be used?
