None Very high X-ray fraction in germanium detector

Hey ,

I am running a simulation using a 511keV point
 source 6.5 cm away from a 20cm thick germanium detector.

I run for 100,000 events and get what seems to be far too many events in the germanium x-ray peak.

I have approx 1300 events at 11keV and only 90 at 500 keV.

It seems that every x-ray is being treated as an energy deposit in its own right, although a real detector would not be able to separate it from the main charge deposited.

does anybody have an idea how to stop it doing that ?

Thanks for any help and apologies if this is really stupid.
