Description

The gamma transitions with E$_{\gamma}$ > 3 MeV from decays of $^{208}$Tl have not been observed and their transition intensities were known only as upper limit values. We measured a ThO$_2$ powder using a 100$\%$ HPGe (High Purity Germanium) detector to obtain more accurate numbers of the transition intensities. This study is expected to help understanding nuclear decay properties of the nucleus and high energy gamma backgrounds in rare decay experiments, such as neutrinoless double beta decay searches. The experimental setup, Monte Carlo simulation studies for detection efficiencies, and preliminary results are going to be presented.
