Outline of Final Research Achievements

Precise measurement of the atomic spectrum of radioactive tungusten isotopes has been awaited to clarify the change of charge radii between these nuclei. In order to do laser spectroscopy for these nuclei, we have developed a gas cell connected on-line to an accelerator. A violet diode-laser system was used to improve sensitivity. With this setup, we plan to measure the isotope shifts in atomic spectra of radioactive tungusten isotopes.
