Abstract
Hyperfine-structure parameters and isotope shifts for the 795-nm atomic transitions in have been measured at CERN-ISOLDE, using the in-source resonance-ionization spectroscopy technique. Magnetic dipole and electric quadrupole moments, and changes in the nuclear mean-square charge radii, have been deduced. A large inverse odd-even staggering in radii, which may be associated with the presence of octupole collectivity, has been observed. Namely, the radius of the odd-odd isotope has been found to be larger than the average of its even- neighbors, . The discrepancy between the additivity-rule prediction and experimental data for the magnetic moment of also supports the possible presence of octupole collectivity in the considered nuclei.
