Parasitic Signals in the Method of Recoil Nuclei Applied to Direct Observation of the 229mTh Isomeric State
Section: Physics experiment techniques
Abstract: We carry out necessary theoretical justifications for the method of recoil nuclei in application to the direct observation of the 229mTh isomeric state. We consider Cherenkov radiation, phosphorescence, and fluorescence in a crystal plate, which is used for collecting the thorium recoil nuclei, and discuss the ways to avoid these parasitic signals in order to successfully reveal 229mTh decay photons
Key words: Th-229, recoil nuclei, isomeric state, -decay, Cherenkov radiation, phosphorescence, fluorescence, magnesium fluoride.
