| Description: |
10 pages, 5 figures, 3 tables ; The changes in the mean-squared charge radii relative to 209 Bi 126 (𝛿⟨𝑟2⟩𝑁,126) and the magnetic dipole and electric quadrupole moments in 214−218 Bi have been measured using the in-source resonance-ionization spectroscopy technique at ISOLDE (CERN). Magnetic moments of odd-odd bismuth nuclei have been analyzed by the additivity relation. Previous tentative spin-parity and configuration assignments based on the 𝛽-decay feeding patterns have been supported. A normal odd-even staggering in charge radii of bismuth isotopes with 𝑁>126 has been observed. The new data for the 𝛿⟨𝑟2⟩ of bismuth isotopes allow a study of the isotonic dependencies in the charge radii, revealing jumps in 𝛿⟨𝑟2⟩132,126 and 𝛿⟨𝑟2⟩134,126 at 𝑍=84. This pattern could be explained by a sudden onset of octupole deformation at 𝑁=132 and 134 when going from polonium (𝑍=84) to astatine (𝑍=85). ; We thank the ISOLDE Collaboration for providing excellent beams.
