Claims

C1strongest claim

We report the first observation of narrow band 1.3 MeV γ radiation from a crystalline diamond micro-undulator. A clear peak was detected with a large sodium iodide scintillation detector close to the expected photon energy of 1.28 MeV.

C2weakest assumption

The detected peak originates from the micro-undulator radiation mechanism in the sinusoidally deformed boron-doped diamond lattice rather than from background processes or other radiation channels, with the Monte Carlo simulation providing the necessary validation of this attribution.

C3one line summary

First observation of narrow-band 1.3 MeV gamma radiation from a boron-doped diamond micro-undulator with 5.0 μm period, confirmed by Monte Carlo simulation matching energy, width and intensity.
