Bremsstrahlung mechanism

It is found that the number of reactions in the Compton backscattering method is about 30 orders magnitude better than the one for bremsstrahlung method for 1021 W cm2-lear w ucts is ome v ion of achieve the valuable and safe products is a subject of global atten-tion [8–12]. Based on the development of ultra-intense femto-sec-ond lasers a new approach of relativistic plasma physics has been opened to study the application of energetic particle beams in var-ious fields [13,14]. The dramatic development of these ultra-in-tense laser techniques and remarkable progress in explaining the laser transmutation mechanisms has offered novel solutions in bremsstrahlung m is indu n of the u arameters ing electron distribution are the laser parameters and characteristics. Previous experiments have characterize importance of the formation of a pre-plasma in the front o Z solid target to accelerate electrons into relativistic energies [23–25]. By focusing these electrons on the solid target, gamma rays will be produced through bremsstrahlung reaction. These gamma rays with a Boltzmann-like energy distribution will partic-ipate in photonuclear reactions. Consequently, photonuclear reac-tions have been considered to be realistic reactions to be used fo
