Description
The gamma decay intensities for E > 3 MeV from the 208Tl decay have 100% uncertainties in the NNDC database. New measurements with smaller uncertainties are desirable for understanding nuclear decay properties of the nucleus and high energy gamma background in rare decay experiments. A ThO2 powder sample was measured with a 100% High Purity Germanium(HPGe) in the Yangyang underground laboratory (Y2L) at the Center for Underground Physics(CUP) to obtain more accurate numbers of the high energy gamma intensities from the 208Tl. The experimental set-up, Monte Carlo simulation studies for detection efficiencies, and a preliminary result will be presented in this poster.
