  • The natural $\ensuremath{\alpha}$-decay of $^{180}\mathrm{W}$ has been unambiguously detected for the first time. The $\ensuremath{\alpha}$ peak is found in a ($\ensuremath{\gamma}$, $\ensuremath{\beta}$, and neutron)-free background spectrum. This has been achieved by the simultaneous measurement of phonon and light signals with the CRESST (Cryogenic Rare Event Search with Superconducting Thermometers) cryogenic detectors. A half-life of ${T}_{1∕2}=(1.8\ifmmode\pm\else\textpm\fi{}0.2)\ifmmode… CONTINUE READING
