Abstract
Isotope shift relative to and hyperfine splitting for have been measured by in-source laser spectroscopy at the 306.77-nm atomic transition. The pronounced shell effect both in radii and magnetic moments in Bi isotopes at has been observed. The isotopic trend of magnetic moment for ground states of even- Bi isotopes has been qualitatively explained by the change in the first-order core-polarization correction. The possible influence of the octupole degree of freedom on the magnetic moment behavior at has been discussed.
