The actual theoretical research investigates the resonant spontaneous bremsstrahlung (RSB) of ultrarelativistic electrons under the condition of scattering on a nucleus in the field of a weak electromagnetic wave. The progression of the functional mechanism indicates the transformation of the intermediate virtual electron into the real particle state. As a result, the initial second order process with accordance to the fine structure constant in the light field productively splits into two consequent first order formations: the laser-stimulated Compton effect and the laser-assisted scattering of an electron on a nucleus. It is important to emphasize that the resonance escalation possesses a possibility to develop within two reaction channels. Therefore, the first channel - delineates the occurrence that correlates to the spontaneous photon emission by an electron with subsequent scattering on a nucleus. The second channel - illustrates the configuration corresponding to the electron scattering on a nucleus with consecutive spontaneous photon emission in the wave field. Moreover, the spontaneous photon radiation angle allocates a single-valued dependency with the resonant frequency for the first channel in contrast to the second displacement that categorizes a composite area with three various resonant frequency magnitudes for the particular emission angle diapason. The project data analysis proposes that the reaction channels do not interfere within the whole range of observation. To summarize, the investigation calculates that the particular cross-section within the resonant ambience significantly exceeds the according cross-section in the approximation of an external field absence. In conclusion, numerous scientific facilities with specialization in pulsed laser radiation (SLAC, FAIR, XFEL, ELI, XCELS) may experimentally validate the computational estimations.

超相对论电子在原子核和弱电磁波场中的共振高能轫致辐射

实际的理论研究是研究超相对论电子在弱电磁波场中散射到原子核的条件下的共振自发轫致辐射(RSB)。功能机制的进展表明中间虚拟电子向真实粒子状态的转变。结果,根据光场中精细结构常数的初始二阶过程有效地分裂为两个随之而来的一阶形成:激光刺激的康普顿效应和电子在原子核上的激光辅助散射。重要的是要强调共振升级具有在两个反应通道内发展的可能性。所以,第一个通道 - 描述与电子自发光子发射以及随后在原子核上散射相关的事件。第二个通道 - 说明与在波场中连续自发光子发射的原子核上的电子散射相对应的配置。此外,自发光子辐射角为第一通道分配了与谐振频率的单值相关性,而第二位移则对具有三个不同谐振频率幅度的复合区域进行分类,以用于特定的发射角音调。项目数据分析提出反应通道在整个观测范围内不干扰。总结一下,调查计算得出,谐振环境中的特定横截面显着超过了近似无外部场的相应横截面。总之,许多专门研究脉冲激光辐射的科学设施(SLAC、FAIR、XFEL、ELI、XCELS)可以通过实验验证计算估计。
