Fission of actinides using a tabletop laser

Funded under: FP5-JRC

Abstract

Powerful tabletop lasers are now available in the laboratory and can be used to induce nuclear reactions. We report the first demonstration of nuclear fission using a high repetition rate tabletop laser with intensities of 10{20} W/cm{2}. Actinide photo-fission has been achieved in both {238}U and {232}Th from the high-energy bremsstrahlung radiation produced by laser acceleration of electrons. The fission products were identified by time-resolved gamma-spectroscopy.
