Tiivistelmä: | The changes in the mean-square charge radius (relative to Bi-209), magnetic dipole, and electric quadrupole moments of Bi-187,Bi-188,Bi-189,Bi-191 were measured using the in-source resonance-ionization spectroscopy technique at ISOLDE (CERN). A large staggering in radii was found in Bi-187,188,189(g), manifested by a sharp radius increase for the ground state of Bi-188 relative to the neighboring Bi-187,189(g). A large isomer shift was also observed for Bi-188(m). Both effects happen at the same neutron number, N = 10(5), 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. |
