摘要：

An activation measurement was recently performed at the TANDEM accelerator of Horia Hulubei National Institute for Physics and Nuclear Engineering in order to determine subbarrier cross sections for the fusion of Li-6 and Pt-194. The irradiated targets were measured using two HPGe detectors in very close geometry. Extensive Monte Carlo simulations were performed for the determination of the efficiency of the setup. MCNP5 [1] was employed to interpolate and extrapolate the experimental efficiencies at the gamma energies of interest while GESPECOR [2] was used to determine the summing correction factors. We describe in detail the two simulations of the setup and give examples of simulated and experimental efficiencies with and without summing corrections.
