I Quasi-Elastic Scattering Peak-Shift

Click For Summary
In quasi-elastic scattering, a diagram of scattered electron energy shows two peaks: one for elastic scattering off the nucleus and another shifted 8 MeV lower due to the binding energy of protons. The 8 MeV shift originates from the elastic scattering off free electrons, not from the nucleus, as bound protons have lower energy than the nucleus itself. Clarification is sought on whether the electrons are interacting with bound protons or losing energy to them. The discussion emphasizes the importance of understanding the energy levels of bound protons in relation to the nucleus. Overall, the relationship between binding energy and scattering outcomes is central to the inquiry.

Clarifying the 8 MeV shift due to the binding energy of the proton in the nucleus
We were told in my particle physics lectures that in a quasi-elastic scattering, in a diagram of scattered electron energy ##E'##-counts corresponding to an electron-nucleus scattering experiment at a fixed detector angle ##\theta##, we would have a peak corresponding to the electrons that have scattered elastically off of the nucleus, and then another peak that is 8 MeV shifted to lower energies due to the binding energy of the proton in the nucleus. Just to be sure, the 8 MeV shift is happening from an elastic-scattering-off-of-free-electrons-peak that is not visible in the diagram, and not from the elastic-scattering-off-of-the-nucleus-peak, since the bound proton has a much lower energy than the whole nucleus, right?

According to binding energy equation, Binding Energy, the bound proton would have a lower energy than the total nucleus. Are you asking if your electrons are breaking apart bound protons or losing energy to bound protons?
 
Thread 'Some confusion with the Binding Energy graph of atoms'
My question is about the following graph: I keep on reading that fusing atoms up until Fe-56 doesn’t cost energy and only releases binding energy. However, I understood that fusing atoms also require energy to overcome the positive charges of the protons. Where does that energy go after fusion? Does it go into the mass of the newly fused atom, escape as heat or is the released binding energy shown in the graph actually the net energy after subtracting the required fusion energy? I...
