+On this site we present a C++ code which can be used to create data tables for the
+doubly differential cross sections for electron-nucleus Bremsstrahlung and pair production. The code consists of two parts: In the beginning there is a header which defines the functions for Bremsstrahlung and pair
+production. These lines have to appear in the beginning of a C++ code. Then the
+functions for Bremsstrahlung and pair production follow which can be placed anywhere
+else in the code.\\
+The function to calculate the doubly differential cross section for Bremsstrahlung can
+be called by
+<code>
+brems(E_kin, omega, Theta_i)
+</code>
+where E_kin denotes the kinetic energy of the incident electron in Joule, omega is the
+frequency of the emitted photon in 1/s and Theta_i is the scattering angle. The function
+to calculate the doubly differential cross section for pair production can be called by\\
+<code>
+pairpr(E_kin, omega, Theta_p)
+</code>
+where E_kin denotes the kinetic energy of the created positron in Joule, omega the frequency
+of the incident photon in 1/s and Theta_p the angle between both.\\
+The code can be downloaded {{en_brems.cpp|here}}.
