Relativistic Expansion of Electron-Positron-Photon Plasma Droplets and Photon Emission
arXiv:1008.3495 · doi:10.1063/1.3499410
Abstract
The expansion dynamics of hot electron-positron-photon plasma droplets is dealt with within relativistic hydrodynamics. Such droplets, envisaged to be created in future experiments by irradiating thin foils with counter-propagating ultra-intense laser beams, are sources of flashes of gamma radiation. Warm electron-positron plasma droplets may be identified and characterized by a broadened 511 keV line.
