Laser Spectroscopy on-line

On-line laser spectroscopy is a versatile tool to determine nuclear ground state properties of short-lived nuclei in a model-independent approach. Hence, it has been implemented and applied at several facilities around the world. The two techniques that have been most often employed are collinear laser spectroscopy and resonance ionization spectroscopy. Both methods have been continuously developed to reach ever higher sensitivity and accuracy. LaserSphere is strongly engaged in collinear laser spectroscopy at ISOLDE and belongs to the COLLAPS collaboration. We have performed the BeTINa experiment at COLLAPS and are collaborating on measurements on magnesium, copper, and gallium isotopes. We have furthermore contributed with high-precision calibrations of the high-voltage supplies at ISOLDE in collaboration with the group of Christian Weinheimer at the University Münster.

At Mainz, a new facility for collinear spectroscopy is being developed - TRIGA-LASER - which is part of the TRIGA-SPEC collaboration. Besides laser spectroscopy, also mass measurements are performed at the TRIGA-TRAP setup. TRIGA-SPEC is the only facility for laser spectroscopy and mass measurements at a nuclear reactor. More details can be found on the TRIGA-SPEC webpage.

On the survey page you will find a nuclear chart with an overview on all laser spectroscopic experiments determining nuclear ground state properties that were reported up to date at the different on-line facilities world-wide.
