The nuclei around Z = 72 - 78 are known as transitional nuclei, exhibiting a multitude of nuclear shapes depending on the neutron and proton numbers (N and Z) [1]. Around N = 116, various theoretical calculations predict prolate deformation for lighter isotopes, passing through γ-soft or triaxial shapes, and reaching oblate shapes in heavier isotopes [2,3]. The evolution of their nuclear...

We have been developing a gas cell-based laser ionization technique for the production of low-energy Radioactive Isotope (RI)-beam in two application schemes. One is to obtain a wide variety of the low-energy RI-beams from high-energy RI-beams provided by the BigRIPS fragment separator at RIKEN. And the other is ongoing phase for the feasibility study of the production of medical...

Resonant laser excitation in atomic spectrum studies unveils nuclear structures. Interactions of the nuclear ground state with the electronic shell induce hyperfine structure (HFS) and isotope shift (IS), enabling precise measurement of nuclear properties such as spin (I), magnetic dipole moment ($μ_I$), electric quadrupole moment ($Q_s$), and changes in mean square charge radii ($δ⟨r^2⟩$)....
