The Compton effect illustrates the particle nature of gamma radiation.
When a gamma quantum bounces off an electron, its energy loss depends on the scattering angle.
This kit comprises two pairs of shell-shaped targets and a central holder with adjustment screws and lead absorber.
These rotationally symmetrical aluminium targets give a high count rate for the two fixed scattering angles of approx. 60° and 90°. With our gamma spectrometer and a standard Cs-137 source, viable difference spectra for both angles can be obtained within an hour. A lead absorber blocks the direct radiation from the source to the detector. Correction for background radiation (including scattered radiation from the table top etc.) is handled by the 518000 software.
The principle behind this device is the old geometric truth that the size of a peripheral angle is defined by the arc it spans. We can thus obtain the same scattering angle over a very large solid angle.
In addition to the Cs-137 Risø source (item no. 510030), the following are required:
514102 Rail for mounting bench
294610 Saddle with Ø 10 mm hole (2 of)
514180 Source holder for mounting bench, simple
518500 Scintillation detector
518000 Multichannel analyser
