Hello Fabio,
Your have a peak around 60 keV but you have also the other gamma peaks
emitted by the daughters of Am-241 by alpha decays : Np-237 and Pa-233
(for instance 86 keV for Np-237 and 312 keV for Pa-233).
As an alternative solution, if you want to simulate the effect of an
Am-241 source, you can always set a 59,54 keV photon source and
normalize by intensity and source activity afterwards (for more complex
cases you can also use source.f routine).
Hope it helps.
Best regards.
Sébastien.
