In-source and in-trap formation of molecular ions in the actinide mass range at CERN-ISOLDE
The use of radioactive molecules for fundamental physics research is a developing interdisciplinary field limited dominantly by their scarce availability. In this work, radioactive molecular ion beams containing actinide nuclei extracted from uranium carbide targets are produced via the Isotope Sepa...

| description | The use of radioactive molecules for fundamental physics research is a developing interdisciplinary field limited dominantly by their scarce availability. In this work, radioactive molecular ion beams containing actinide nuclei extracted from uranium carbide targets are produced via the Isotope Separation On-Line technique at the CERN-ISOLDE facility. Two methods of molecular beam production are studied: extraction of molecular ion beams from the ion source, and formation of molecular ions from the mass-separated ion beam in a gas-filled radio-frequency quadrupole ion trap. Ion currents of U<math altimg="si66.svg" display="inline" id="d1e3016"><msup><mrow/><mrow><mo>+</mo></mrow></msup></math>, UO1−3<sup loc="post">+</sup>, UC1−3<sup loc="post">+</sup>, UF1−4<sup loc="post">+</sup>, UF1,2O1,2<sup loc="post">+</sup> are reported.

Ion currents of U$^+$, UO$_{1-3}^+$, UC$_{1-3}^+$, UF$_{1-4}^+$, UF$_{1,2}$O$_{1,2}^+$ are reported. Metastable tantalum and uranium fluoride molecular ions are identified.
