The spectrum of emission of a composite particle with one degree of freedom in a constant electric field is obtained in the paper. The effectiveness of emission of such particle is compared with the structureless particle having the same parameters. The power of emission of composite particle is several digits more than that of a structureless particle. https://www.jmannino.com/quick-save-Canon-imageCLASS-MF227dw-Monochrome-Multifunction-Laser-Printer-great-choice/
