How a group of nucleus can act as a circular aperture

Click For Summary
SUMMARY

This discussion focuses on the application of the electron diffraction equation, sin(theta) = 1.22lambda/d, in measuring the radius of nuclei and understanding how a group of nuclei can function as a circular aperture. The user seeks clarification on the derivation of this diffraction equation, indicating that existing resources are too complex. The Wikipedia article on Fraunhofer diffraction is recommended as a valuable resource for further understanding.

PREREQUISITES
  • Understanding of electron diffraction principles
  • Familiarity with the equation sin(theta) = 1.22lambda/d
  • Basic knowledge of circular aperture diffraction
  • Ability to interpret scientific literature on diffraction
NEXT STEPS
  • Study the derivation of the diffraction equation in detail
  • Explore the principles of Fraunhofer diffraction
  • Research the role of circular apertures in wave optics
  • Examine practical applications of electron diffraction in nuclear physics
USEFUL FOR

Students and researchers in physics, particularly those focusing on nuclear physics, optics, and electron diffraction techniques.

So I have been learning about measuring nuclei radius using electron diffraction, using sin(theta)=1.22lambda/d, doing some research I found out that is the equation for circular aperture diffraction but I don’t really understand how a group of nucleus can act as a circular aperture. Also is there anyone can show me the derivation of the diffraction equation, the only one example that I could find was way out of my league, hope someone can enlighten me on that, thank you
