Outline of Final Research Achievements

A grating type Ti:Sapphire laser system was developed to investigate highly efficient ionization scheme for high resolution resonance ionization spectroscopy of short/long-lived radioisotopes and its application to trace analysis. Basic performances such as its resolution were evaluated from results in high resolution resonance ionization spectroscopy of stable isotopes such as Nb, Ti and Zr using narrow band pulsed Ti:Sapphire laser system. These Ti:Sapphire laser systems were installed at accelerator research facilities at RIKEN, Japan and the University of Jyvaskyla, Finland for future on-line experiments.
