| Research Abstract |
By measuring the atomic spectra of tungsten isotopes precisely, information on the deformation of these nuclei can be obtained. For this measurement, we have developed an on-line method, in which the isotopes being produced by an accelerator are captured in a gas cell and are subsequently irradiated by laser. With this method, we have succeeded in measuring the atomic spectra of stable tungsten isotopes, but it has been found that further improvements of the sensitivity are needed for the measurements of unstable isotopes.
