Question Deposited energy for hundreds of KeV neutrons hit a silicon detector

Hi, Geant4ers,

There is a basic question I'd like to ask here. My simulation is hundreds of KeV neutrons hit a silicon detector.

I'm confused about the deposited energy returned by the "GetEdep()". From the section of " Non-Ionizing Energy Loss due to Coulomb Scattering " on the physics reference manual, I think the deposited energy is the ionized energy of a Coulomb scattering because Lindhard formula has been included there.

While, for a 100s KeV of neutron, it scatters a silicon detector elastically via strong interaction I think. So, it's a different process than Coulomb scattering.

My question is, in my case, 100s KeV of neutrons, what's the deposited energy returned from "GetEdep()" ? It's same as ionized energy as the case of Coulomb scattering ? Or something else ?

Let me clarify a little bit more. Imaging a 100KeV neutron hitting a silicon detector, a silicon nucleus will be hit and get some recoiled energy. According to the Lindhard theory, this recoiled silicon will produce some electronic equivalent ionized energy and nuclear recoil energy to other silicon nucleus.

The energy deposited in my silicon detector is the electron equivalent energy, not the recoil energy of the first silicon being hit, right ?

Thanks !

Best, Junhui
