Abstract	High brightness beams of gamma rays produced with laser Compton scattering have the potential to realize photo-transmutation through (&gamma;,n) reaction, implying an efficient method to dispose long-lived fission products. Preliminary investigations have been carried out in understanding the feasibility of development of a transmutation facility to repose nuclear waste. A laser Compton scattering experimental setup based on a storage ring started to generate gamma-ray beams for studying the coupling of gamma photons and nuclear giant resonance. This paper demonstrates the dependency of nuclear transmutation efficiency on target dimensions and gamma ray features. <sup>197</sup>Au sample was adopted in our experiment, and experimental results correspond to the theoretical estimations.
