^{197}Au(γ,\,xn;\,x\,=\,1\thicksim9) Reaction Cross Section Measurements using Laser-Driven Ultra-Intense γ-Ray Source

We present a new method for the measurements of photonuclear reaction flux-weighted average cross sections and isomeric ratios using a laser-driven bremsstrahlung \gamma-ray source. An ultra-bright ultra-fast 60\,\thicksim\,250 MeV bremsstrahlung \gamma-ray source was established using the 200 TW laser facility in the Compact Laser Plasma Accelerator Laboratory, Peking University, which...
