Targets for precision spectroscopy with multiply-charged actinide molecules — •Lennard Marek Arndt1, Jonas Stricker1,2, Dennis Renisch1,2, and Christoph Emanuel Düllmann1,2,3 — 1JGU Mainz Germany — 2HI Mainz, Germany — 3GSI Darmstadt, Germany
Multiply-charged actinide molecules offer promising new opportunities for tests of fundamental symmetries by precision spectroscopy. The production of multiply-charged ions was reported via laser ablation of chemically tailored targets that contain all elements desired in the molecular ion. We demonstrate target production via electroplating and direct synthesis. We also present ToF spectra from laser ablation of actinide molecular ions. Ablation of a ThF4 target and an uranium foil yielded ThF2+ and UO3+ respectively, both isoelectronic to RaF and thus, sensitive to nuclear Schiff moments.
