Large Shape Staggering in Neutron-Deficient Bi Isotopes
The changes in the mean-square charge radius (relative to $^{209}$Bi), magnetic dipole, and electric quadrupole moments of $^{187,188,189,191}$Bi were measured using the in-source resonance-ionization spectroscopy technique at ISOLDE (CERN). A large staggering in radii was found in $^{187,188,189}$B...

| description | The changes in the mean-square charge radius (relative to $^{209}$Bi), magnetic dipole, and electric quadrupole moments of $^{187,188,189,191}$Bi were measured using the in-source resonance-ionization spectroscopy technique at ISOLDE (CERN). A large staggering in radii was found in $^{187,188,189}$Big, manifested by a sharp radius increase for the ground state of $^{188}$Bi relative to the neighboring $^{187,189}$Big. A large isomer shift was also observed for $^{188}$Bi$^m$. Both effects happen at the same neutron number, $N = 105$, where the shape staggering and a similar isomer shift were observed in the mercury isotopes. Experimental results are reproduced by mean-field calculations where the ground or isomeric states were identified by the blocked quasiparticle configuration compatible with the observed spin, parity, and magnetic moment. |
