Abstract: (Elsevier)
The 169Tm nuclide has first nuclear level at 8.41 keV with magnetic type transition to the ground state and, therefore, can be used as a target nucleus for the search of resonant absorption of solar axions. We plan to use a Tm-containing crystal of a garnet family Tm3Al5O12 as a bolometric detector in order to search for the resonant absorption of solar axions. With this perspective in mind, a sample of the Tm3Al5O12 crystal was grown and tested for its bolometric and optical properties. Measurements of chemical and radioactive contaminations were performed as well. In this paper we present the test results and estimate the requirements for a future low-background experimental setup.Note:
