Laser Spectroscopy of Thulium-169 — •Hendrik Bodnar, Julian Palmes, Wilfried Nörtershäuser, and Kristian König — Institut für Kernphysik, TU Darmstadt

Laser spectroscopy is an established way to obtain information about the charge radius and the electromagnetic moments of a nucleus and has been applied to many isotopes all across the nuclear chart. In preparation for the investigation of short-lived Tm isotopes at the proton dripline [1], the stable 169-Tm was investigated at the Collinear Apparatus for Laser Spectroscopy and Applied Physics (COALA) at the Institute of Nuclear Physics at TU Darmstadt. Singly charged thulium was produced with a surface ionization source. Several transitions from the ionic ground state in the wavelength range between 340 nm and 425 nm have been studied and the hyperfine structure was analyzed. This allowed the selection of a suitable transition for efficient studies of rare isotope beams. Funding from the BMBF under contracts 05P21RDCI1 and 05P21RDFN1 is acknowledged. [1] B.
