Interactions of Photons with Matter - MIT OpenCourseWare

ocw.mit.edu

In Compton scattering, the incoming gamma-ray photon is deflected through an angle θ with respect to its original direction. The photon transfers a portion of its energy to the electron (assumed to be initially at rest), which is then known as a recoil electron, or a Compton electron. • All angles of scattering are possible.

Area = y dx. This is awkward, because near the end the height of the region changes from a constant y = b to the height of the circle y = √ a2 − x2. What if we integrate with respect to y?
