Hi Debora,
<div><br>
</div>
<div>for Isotopes like In-111 or I-123 you should use the ion as the particle in</div>
<div>the source description and leave the energy type as Mono.</div>
<div><br>
</div>
<div>See also the attached macro, which I used for the EduGATE - Spectro example.</div>
<div>I also copy the macro here in case there is a problem with attachments,</div>
<div>while sending a reply to the “gate-user-list”.</div>
<div>(The aliases like {Ion_Z_val} and {Ion_A_val}, etc are replaced by the selection </div>
<div>from the menu of the GUI running the example as shown in the Readme).</div>
<div><br>
</div>
<div>Hope this is helpful for you,</div>
<div><br>
</div>
<div>Kind regards,</div>
<div><br>
</div>
<div>Uwe Pietrzyk</div>

<div>Dear GATE users,<br>
<br>
</div>
How should I define the energy type for I-123 and In-111 in my SPECT simulations?<br>
<br>
</div>
For Tc-99m, I'm using :<br>
</div>
particle gamma<br>
</div>
energytype Mono<br>
</div>
monoenergy 141. keV<br>
</div>
setForcedHalfLife 6. h<br>
<br>
</div>
but In-111 has two photopeaks (171 and 245 keV) and I-123 has a significant amount of photons (abundance 3.1%) with a higher energy than the photopeak (159 keV), so I'm not sure how to define my source in either of the cases, I-123 and In-111.<br>
<br>
</div>
Thanks.<br clear="all">
