MONOCHROMATIC GAMMA-RADIATION EMITTED BY A RELATIVISTIC ELECTRON MOVING IN A CARBON NANOTUBE

We consider the spontaneous emission of a relativistic electron moving inside a single-layer carbon nanotube and interacting without delay w ith the screened nuclear charges of the carbon atoms. Electrons with a n energy of 200 MeV may emit in their propagation direction quanta aro und 6 MeV in energy and some 5 keV in linewidth. The results obtained allow one to consider carbon nanotubes a new source of hard, monochrom atic, highly directional radiation potentially suitable for the implem entation of selective photonuclear reactions.
