Question What is the meaning of the energy deposition of compton scattering?

Dear All,

I am confused with the energy deposition with gamma transportation. I could not understand why do we have the energy deposition during the process of compton scattering process? (using step->GetTotalEnergyDeposit()). Where is this energy from? And what is this meaning?

 Also the kinetic energy of secondary electron is not equal to the (PostPoint->KinE- Prepoint->KinE) of the gamma ray.

I tried several EM physics, e.g. Standard, Livermore, Penelop, etc. They all have this issue. And also, I was thinking this might because of the secondary production cut. And I tried to set the cut to a very low value, e.g. 0.00001 * nm. But Nothing changed. The step->GetTotalEnergyDeposit() can be up to 1000 eV. Which can not explained by the production cut.

Is there anyone have an idea on this?

Any help will be very appreciated.

Thank you very much.

Best, Chunhui
