Web26 de jun. de 2013 · Fermi/LAT has detected long-lasting high-energy photons (>100 MeV) from gamma-ray bursts (GRBs), with the highest energy photons reaching about 100 GeV.One proposed scenario is that they are produced by high-energy electrons accelerated in GRB forward shocks via synchrotron radiation. We study the maximum synchrotron … WebWhen high-energy X-rays (which have energies much larger than 30keV) are incident on a material, the penetration ability of the material decreases due to a reduced mass attenuation coefficient in the materials.The mass attenuation coefficient expresses the ability of a material to be penetrated by energy, and it decreases at higher energies. Therefore, the …
