The RAON radioactive ion beam facility with resonant ionization laser ion source and a dedicated collinear fast beam laser spectroscopy facility will be the ideal place to carry out challenging, state-of-the-art experiments. One such experiment is to investigate nuclear structure beyond quadrupolar deformation. The neutron-deficient La isotopes are in the mass region where an axially asymmetric shape of nuclei is predicted theoretically. To clarify the deformation of 129La and even more neutron-deficient La isotopes, we are now planning to extend the laser spectroscopy to these nuclides.
