Dear Lise,

I have done some simulations  to reproduce the problem that you get but I do
 not get an overestimated line at 778 keV as you do.
In my case I just simulate the radioactive decay of  152Eu ions in Vaccum.
When the decay occurs I register the secondary. The full decay chain is treated. To understand your problem I would need more insight on how 
you do your simulation.

Laurent
