PURPOSE: To show how a photocell can generate electric power.
DESCRIPTION: A software program by CUPS called Nuclear and Particle Physics
Simulations has a chapter on General Radiation in Matter. In this software
simulation an incident gamma ray hits a target material. After the collision
an electron is released from the material and the reflected gamma is scattered at some
angle.
The probability of a given gamma-ray scattering in a given direction was developed in 1934
utilizing
relativistic quantum mechanics. The result, known as the Klein-Nishina Equation expresses
the probability
of a gamma ray scattering off an outer shell electron through some angle.
EQUIPMENT: Software and computer with projector.
