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.
