The problems of spin-polarized free-electron beam interaction with electromagnetic wave at electron-spin resonance conditions in a magnetic field and of superradiant spin-flip radiative emission are analyzed in the framework of a comprehensive classical model. The spontaneous emission of spin-flip radiation from electron beams is very weak. We show that the detectivity of electron spi... https://www.chiggate.com/jerome-brown-philadelphia-eagles-mitchell-ness-1990-legacy-jersey-discount/
