Questions about Compton Scattering

Click For Summary

Discussion Overview

The discussion revolves around the experimental setup used by Arthur Compton to measure the wavelength shift in Compton scattering. Participants explore different equipment and methods employed in the experiments, including cloud chambers, Bragg spectrometers, and ionization chambers.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the specific equipment Compton used, mentioning conflicting sources regarding the use of Bragg spectrometers and ionization chambers.
  • Another participant asserts that Compton utilized a cloud chamber, referencing a Nobel lecture for further details.
  • A follow-up question addresses the localization of the scattering target within the cloud chamber and the relationship between the recoiling electron's angle and the secondary ray's angle.
  • There is a request for clarification on whether an image from the Nobel lecture is a simplification of another referenced image.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the specific equipment used by Compton, as different methods are mentioned and explored without resolution.

Contextual Notes

Some assumptions about the experimental setup and the interpretation of the images referenced remain unaddressed, and the discussion does not clarify the precise definitions of terms used.

What equipment Compton used to measure the wavelength shift in your experiment ? Some links talk about the use of bragg spectrometer others about the use of ionization chambers.


In this link have some illustrations of spectras resultants of Compton experiments

The peak of unmodified rays, its caused by the interactions with electron close to the nucleus?
 
Physics news on Phys.org
anyone?
 
He used a cloud chamber - see pp 187, 188 http://nobelprize.org/nobel_prizes/physics/laureates/1927/compton-lecture.pdf
 
thanks for the link.

The target for the primary X-rays ("scattering target") process is localized in the center of the chamber? Compton used the angle of recoiling electron to measure the angle of secondary ray, using this relation \cot\frac{1}{2}\delta=\tan\theta ?

The shown image in the nobel lecture is a
it is a simplification of this image?
