Photoelectrons do not seem to be the initial gamma energy minus binding energy

[Richard_Foster]

In the simplified case of shooting a 277eV gamma into A simple stack of basically Silicon (PV-CAP=1nm of SiO2, PV-MBE=5nm Si and PV-Silicon=2um Si).
What I believe to be the photoelectrons being produced do not seem to be 277eV-Binding Energy (Data From G4AtomicShells for Si 1844.0eV 154.0eV 104.0eV 104.0eV 13.46eV 8.15eV).

In the first three events of my run I get for 277eV Gammas.

Event0. Photo eDep=13.07eV
e- 95.6eV
e 168.33eV

Event1. Event0. Photo eDep=33.81eV
e- 29.25eV
e- 88.49eV
e- 125.45

Event2. Photo eDep=20.15eV
e- 87.83eV
e 169.02eV

The all add up to 277eV. I assume one of the electrons in each event should be an ejected photoelectron and the others auger or C-K electrons. But none of the electrons is equal to 277eV-Binding Energy.
Below is a what I am retrieving from my step actions that corresponds to the three events listed above.

Hello,

yes, this is expected - binding energy is subtracted from the ejected electron energy.

Hi Vladimir,
Thank you for the response.

According to the Physics Reference Manual, The Energy of the ejected photoelectron should be equal to the incoming photon energy (277eV) minus the closest shell energy for the material (154eV for silicon), making the ejected photoelectron equal to 123eV. A 123eV electron is energetic enough to be tracked as a new secondary particle, but none of the electrons I see are emerging from the phot process are equal to 123eV.

So I am humbly still confused.
