Hi Monalisha,

As far as I know, one (or the only) way to deal with the sum peak is to simulate an ion particle instead of mono-energetic sources.

To do so, you'll have to define your source with the code (example with a Na-22 source) :

/gps/particle ion

/gps/ion 11 22 0 0

/gps/energy 0.0 keV

(and the commands for the shape, position, etc ... of the source)

Following this link (http://hypernews.slac.stanford.edu/HyperNews/geant4/get/docsexamples/499.html?inline=-1) you'll see that they recommand to look at the example 'radioactive decay' for more informations (I don't know the name in your Geant4 version).

Again, I'm no expert, I don't know if there is other way to deal with sum peak, but it might be a start.
