| 摘要 |
An electron beam and a positron beam accelerated to the same energy are caused to join into a confluence in the same direction by a magnet for joining electrons and positrons, and positronium molecules or beam-shaped para-positroniums of the same phase cooled to transient Bose-Einstein condensation or the vicinity thereof are formed on the axis of confluence by a beam focusing solenoidal coil, thereby simultaneously generating gamma-ray lasers of two wavelengths which accompany annihilation caused by self-stimulated radiation, namely a forward GASER, which is a monochromatic gamma-ray laser having a photon energy of greater than several MeV and a backward GASER, which is a monochromatic gamma-ray laser having a photon energy of less than 200 keV.
