The Klein-Nishina Formula in Qed and Anti Compton Effect (2).

Authors: Abdullah Shehada

When the photon beam is coming on the material , it's will be attenuation in this material ( the number of the photons will be decreased when it's go out the material ) this attenuation is related with the energy 's photon and also the kind of the material( density ). This attenuation is the result of many kinds of reactions between the photon and the material 's electrons ( mainly ) , one of this kinds is : Compton reaction. In Compton effect : the photon is loses part of it's energy in each reaction with the electrons , and this photon will disappear when it loses all of it's energy . But in this work the opposite is occurs , wherein the cross-section may takes negative values at some values of the ration between photon energy and electron mass energy. consequently , by using the exponential equation we will find the photons in the beam is increases ( exponential increases ) ( the number of photons is increases and maybe also the photon energy do ) , so we obtained the same effect as the laser effect , and we can use this effect in many applications
