WebEnergy absorption is defined as the surface below the load-displacement curve. The average load is identified as one of the determination parameters of absorbed energy capability based on the definition of energy absorption and peak load value, which was attained in the first step of a quasi-static test. Webthe absorber are recoiled by incident photons, which deviate and give off a part of their energy as kinetic energy of the recoil electrons. Thus these incoherently scattered quanta have lower energy (i.e. lower frequency) than the incident quanta. The relation between the mass scattering coefficient and the scattering per electroti,
