Multiply charged uranium monoxide as a versatile probe of fundamental physics
Jonas Stricker, Konstantin Gaul, Paul Fischer +8
Multiply charged actinide molecules provide a unique platform to study fundamental physics and the chemical bond under extreme conditions. Beyond the inherently large relativistic…
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…
Influence of carbon dioxide and water concentration on terbium thin films produced by Molecular Plating
Ernst Artes, Primiana Cavallo, Tobias Häger +8
Terbium and thulium thin films were produced by Molecular Plating under controlled conditions to elucidate a possible influence of water and carbon dioxide present in the plating s…
Study of thorium in hypersonic gas jets: Ionization potentials of Th and Th
A. Claessens, F. Ivandikov, M. Brasseur +10
Laser ionization spectroscopy was performed on both neutral and singly ionized Th with the aim of identifying the nuclear-clock isomer in the singly charged ionic state of…
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…
