论文摘要
本文考虑了基于独特的仪器（欧洲X射线无电子激光器（E-XFEL））在基本物理学领域进行实验研究的可能性。用$ e \ sim〜（1-100）\，\ mbox {gev} $带有X射线光子的反应$γ+γ\ to e^{+}+ e^{ - } $横断面的gamma Quanta的横截面。审查了反应$γ+γ\ to e^{+}+ e^{ - } $产品的实验登记的可能性。同样，估计了伽马射线与E-XFEL光子脉冲之间的相互作用的光学深度。讨论了天体物理应用。
The possibility of performing the experimental research in the field of fundamental physics based on the unique instrument -- European X-ray Free Electron Laser (E-XFEL) is considered in this paper. The calculations of the reaction $γ+ γ\to e^{+} + e^{-}$ cross section for gamma quanta with $E \sim~(1-100)\,\mbox{GeV}$ energy with X-ray photons are performed. The possibility of experimental registration of reaction $γ+ γ\to e^{+} + e^{-}$ product are reviewed. Also, the optical depth of the interaction between gamma-rays with the E-XFEL's photon pulses is estimated. Astrophysical applications are discussed.
