Questions about Compton Scattering

Click For Summary
Compton used a cloud chamber to measure wavelength shifts in his experiments, as detailed in his Nobel lecture. Discussions highlight the use of Bragg spectrometers and ionization chambers in different contexts. The peak of unmodified rays results from interactions with electrons near the nucleus. The scattering target for primary X-rays is centered in the chamber, and Compton measured the angle of recoiling electrons to determine the angle of secondary rays. Illustrations of spectral results from Compton experiments are available through provided links.

What equipment Compton used to measure the wavelenght 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?

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?

From the BCS theory of superconductivity is well known that the superfluid density smoothly decreases with increasing temperature. Annihilated superfluid carriers become normal and lose their momenta on lattice atoms. So if we induce a persistent supercurrent in a ring below Tc and after that slowly increase the temperature, we must observe a decrease in the actual supercurrent, because the density of electron pairs and total supercurrent momentum decrease. However, this supercurrent...
