Description

In the experiment P6.5.6.1, the Compton scattering of γ quanta with the energy E0 = 667 keV at the quasi-free electrons of an aluminium scattering body is investigated. For each scattering angle ϑ, a calibrated scintillation counter records one γ spectrum with and one without aluminum scatterer as a function of the respective scattering angle. The further evaluation utilizes the total absorption peak of the differential spectrum. The position of this peak gives us the energy E(ϑ). Its integral counting rate N(ϑ) is compared with the calculated effective cross-section.
