Developments in laser spectroscopy at the Jyväskylä IGISOL

This paper describes the programme of work on laser spectroscopy of radioactive atoms being carried out at the IGISOL facility by a Birmingham-Jyväskylä-Manchester collaboration. The advantageous features of the ion guide ion source, combined with an ion beam cooler-buncher allows a broad range of studies to be pursued. Highlighted in this presentation are collinear beams laser spectroscopic measurements on Zr and Y isotopes, and charge radii determinations for two 8- isomers in 130Ba and 176Yb. A laser ion source capability called FURIOS is being developed for the IGISOL which will not only provide isobarically pure beams for experiments, but also allow in-source laser spectroscopy of short-lived isomers of heavy elements.
