自旋效应在同步辐射理论中的基础

Effective spectrum width of the synchrotron radiation

For an exact quantitative description of spectral properties of synchrotron radiation (SR), the concept of effective width of the spectrum is introduced. In the most interesting case, which corresponds to the ultrarelativistic limit of SR, the effective width of the spectrum is calculated for the polarization components, and new physically important quantitative information on the structure of spectral distributions is obtained. For the first time, the spectral distribution for the circular polarization component of the SR for the upper half-space is obtained within classical theory.

自旋翻转同步辐射的讨论

Discussion on spin-flip synchrotron radiation

量子自旋翻转跃迁在同步辐射理论中具有重要的意义。为了更好地理解这种现象的本质，有必要从观察中排除与电荷辐射有关的影响。这一事实解释了建议选择的自旋翻转辐射模型，即在均匀磁场中运动的电中性狄拉克-泡利粒子的辐射形式。已知在这种情况下，量子理论中的总辐射受自旋翻转跃迁的制约。这个想法是，自旋翻转辐射表示为一个非稳态过程与自旋进动。我们将说明如何构造具有Dirac-Pauli方程精确解的BMT理论中经典自旋进动方程的解，从而找到量子自旋翻转跃迁与经典自旋进动的联系。

Coherent emission of $γ$ quanta by synchrotron radiation excited nuclei: geometry of nearly backward scattering

A possibility of further development of Synchrotron Mössbauer Source (SMS) of $^{57}$Fe 14.4 keV radiation is considered. The principles and detailed description of the SMS device is given in Refs. Phys. Rev. A 84, 053851 (2011) G. V. Smirnov et al, J. Synchrotron Rad., v. 19, 559 (2012) V. Potapkin et al. The perfect crystal of Iron Borate, FeBO$_{3}$, is the central element of this device. The coherent nuclear fluorescence of IB crystal illuminated by synchrotron radiation produces the sharply directed beam of 14.4 keV Mössbauer radiation from the crystal set at the pure nuclear Bragg reflec…

Quantum deformation of the angular distributions of synchrotron radiation. Emission of particles in the first excited state

The exact expressions for the characteristics of synchrotron radiation of charged particles in the first excited state are obtained in analytical form using quantum theory methods. We performed a detailed analysis of the angular distribution structure of radiation power and its polarization for particles with spin 0 and 1/2. It is shown that the exact quantum calculations lead to results that differ substantially from the predictions of classical theory.
