Silicon Photon Cross Section Using Logarithmic Scale

A logarithmic scale is a nonlinear scale used when there is a large range of quantities. Common uses include the earthquake strength, sound loudness, light intensity, and pH of solutions. It is based on orders of magnitude, rather than a standard linear scale, so each mark on the scale is the previous mark multiplied by a value. If both the vertical and horizontal axes of a plot are scaled logarithmically, the plot is referred to as a Log/Log plot. In [4] we learned about the Cartesian scale graphs and study the silicon photon absorption (Si photon) cross section. Before reading this paper you may want to review that research. In this study we will learn how to plot quantities on a new type of graph called a logarithmic graph. We will see how this can make it easier to determine the functional relationship between certain quantities. We will motivate logarithmic graphs using silicon photon absorber data. In this study we choose the silicon element to study the Log/Log (scattering coherent, scattering incoherent, photon electric absorption, total attenuation with coherent, total attenuation without coherent and mass energy absorption). The photon absorber data, pair production in nuclear field (cm^2/g) and pair production in electron field (cm^2/g) for silicon photon are also discussed.
