The term ‘cross section’ is a physicists term that we will be using throughout the quarter to describe the interaction of radiation with matter. This term comes from the notion that when particles interact, the strength of their interaction can be represented by the collision of two hard...
An radioactive gamma source produces an electron positron pair in an absorber. The electron/positron pair produce tracks in a drift chamber that has a field of 0.2 weber/m2. The radius of the drift is 2.5 X 10-2m. Using the equation for momentum of a particle given a bending radius of...
Homework Statement
X-ray beam with wavelenth= 1 X 10-10m and a gamma-ray beam from a Cs137 sample with wavelength= 1.88 X 10-12m. If the radiation scattered form free electron is viewed at 90 deg to the incident beam
a) What is the Compton wavelength shift in each case?
b) What kinetic...
