  • Abstract.For the first time ancient Roman lead was used to grow a crystal of PbWO4 , and this crystal has subsequently been used as a cryogenic particle detector. The new device provides independent readout of heat and scintillation light and is able to discriminate between $ \beta/\gamma$ interactions and alpha interactions down to few keV. Stringent limits on the $ \alpha$ decays of the lead isotopes are presented. In particular a limit of $ T_{1/2}>1.4\cdot 10^{20}$ y at a 90% C.L. was… CONTINUE READING
