Undergrad Plasmonic - Dielectric function

Click For Summary
The discussion focuses on the lack of research material regarding the dielectric function of lead (Pb) in high-frequency regimes. The original poster seeks values related to lead's electrical permittivity and its ability to inhibit gamma rays in x-ray applications. Clarifications were made distinguishing lead (Pb) from palladium (Pd). Suggestions were provided to explore Electron Energy Loss Spectroscopy (EELS) as a method to estimate the dielectric function of metals. Resources and links for further research on measuring the dielectric function using EELS were shared.

TL;DR
reference values and graphs
Regarding the electrical permittivity of the metal in a high frequency regime, I cannot find research material related to the lead dielectric function (PD). I can't get the matatrial as values, I'll let you comment on that. I know that Pd can inhibit the amount of gamma rays in the x-ray case, but I would like to know about values related to that.

Could you explain a bit more? What does PD stand for? Is Pd Palladium? By lead, do you mean the element?

This element I'm saying: https://en.wikipedia.org/wiki/Lead

Right. So you want the dielectric function of lead or Pb (not Pd).

The best way might be to look at EELS-spectra (Electron energy loss spectra). They can give you a good estimate of the dielectric function of metals, I believe.
Google "EELS Atlas". Might help.
Otherwise there should be optical measurements, but I don't know so much about that.
 

Thread 'One does not “prove” the basic principles of Quantum Mechanics'

I am slowly going through the book 'What Is a Quantum Field Theory?' by Michel Talagrand. I came across the following quote: One does not" prove” the basic principles of Quantum Mechanics. The ultimate test for a model is the agreement of its predictions with experiments. Although it may seem trite, it does fit in with my modelling view of QM. The more I think about it, the more I believe it could be saying something quite profound. For example, precisely what is the justification of...
