Photoelectric effect - scattering differential cross section

Click For Summary

Discussion Overview

The discussion centers around the differential cross section for the photoelectric effect, with participants seeking and providing references for further reading on the topic. The scope includes theoretical aspects and references to specific research papers.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant asks for clarification on the differential cross section for the photoelectric effect and requests relevant papers.
  • Another participant references a specific paper by G. Petite et al. that discusses the cross section for various photon absorption processes, including the photoelectric effect.
  • There is a request for clarification regarding which formula from the referenced paper is relevant to the discussion.
  • A later reply questions the understanding of the term "differential cross-section" and suggests that the first equation in the paper should be clear.

Areas of Agreement / Disagreement

The discussion does not reach a consensus, as participants express differing levels of understanding and clarity regarding the differential cross section and its representation in the referenced paper.

Contextual Notes

There are indications of assumptions about participants' familiarity with the concept of differential cross sections and the specific equations in the referenced paper, which may not be universally shared.

What is the differential cross section for photo-electric effect? Is there a paper that explains this in more detail?
Thanks in advance for any responses!

G. Petite et al. Phys. Rev. B v.45, p.12210 (1992). They also give the cross section for 2-photon, 5-photon, and 10-photon absorption process.

That one? Which formula?

Er... you do know what a "differential cross-section" is, don't you? I thought Eq. 1 is that obvious?
