Exploring $α$ - and $β$ -decay-induced quenching of the $^{229}$ Th nuclear-clock isomer in solid-state hosts

Y. Elskens, M. Athanasakis-Kaklamanakis, S. Arasada Pradeep +52

The radiative decay dynamics of an ensemble of $^{229 m}$ Th nuclei embedded in CaF $_{2}$ and MgF $_{2}$ is investigated. The isomer is populated through $β$ decay of $^{229}$ Ac…

High-Resolution Laser Spectroscopy on the Hyperfine Structure of $^{255}$ Fm (Z=100)

M. Urquiza-González, M. Stemmler, T. E. Albrecht +36

We report on high-resolution laser spectroscopy of $^{255}$ Fm ( $T_{1/2} = 20$ h), one of the heaviest nuclides available from reactor breeding. The hyperfine structures in two diffe…
