X-Ray Diffraction: Why Doesn't It Eject Electrons?

Click For Summary
SUMMARY

X-ray diffraction does not primarily eject electrons; instead, it causes electrons to oscillate at the same frequency as the X-ray. While X-rays possess sufficient energy to eject electrons from atoms or molecules, the typical experimental setup for X-ray diffraction focuses on detecting diffracted X-rays rather than emitted photoelectrons. In contrast, using an electron analyzer in a vacuum for X-ray photoemission spectroscopy will yield detectable photoelectrons, confirming that both processes can occur but are context-dependent.

X-ray has enough energy to eject the electron in the atom, molecule etc. But in the x-ray diffraction electron does not eject, only oscillate with the same frequency as X -ray,why? Why does not x-ray eject the electron?

Some of them do. Both processes happen, you can just ignore one if you are not interested in it.

This is not correct. There's nothing that says that electrons are also not ejected.

The experimental setup typically is looking only for the diffracted x-ray, i.e. it has some photodetector, not an electron analyzer. So of course the setup will not detect any emitted photoelectrons, because that is not the purpose of an x-ray diffraction experiment.

If you do the same thing in vacuum, and you have an electron analyzer designed to do a x-ray photoemission spectroscopy, I can almost guarantee you that you WILL detect photoelectrons.
