The appearances of the resonant spontaneous emission of ultrarelativistic electrons in the field of a nucleus and a laser

The contemporary theoretical investigation researches the resonant spontaneous bremsstrahlung (RSB) of ultrarelativistic electrons in the field of a nucleus and a laser. The considered process maintains prospect to progress in two observable reaction channels. The academic study scrutinizes specifically the resonant kinematics of the procedure mechanical development. The examination indicates a significant preponderance of one reaction channel over the second alternative. Moreover, the resonant differential cross section of the RSB prominently exceeds the corresponding differential cross section in the absence of the external field. (paper)
