Targets for precision spectroscopy with multiply-charged actinide molecules — •Lennard Marek Arndt¹, Jonas Stricker^1,2, Dennis Renisch^1,2, and Christoph Emanuel Düllmann^1,2,3 — 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.
