High-Resolution Laser Spectroscopy on the Hyperfine Structure of Fm (Z=100)
M. Urquiza-González, M. Stemmler, T. E. Albrecht +36
We report on high-resolution laser spectroscopy of Fm (h), one of the heaviest nuclides available from reactor breeding. The hyperfine structures in two diffe…

Laser fluence-dependent production of molecular thorium ions in different charge states for trapped-ion experiments
Jonas Stricker, Jean Velten, Valerii Andriushkov +8
Thorium ions and molecules, recognized for their distinctive nuclear and atomic attributes, are central to numerous trapped-ion experiments globally. Our study introduces an effect…
