$β$-delayed fission ($β$DF) decay of a low-spin (ls) and a high-spin (hs) isomer in $^{188}$Bi was studied at the ISOLDE facility at CERN. Isomer-selective laser ionization and time gating were employed to investigate each isomer separately and their $β$DF partial half-lives were determined: $T_{1/2\mathrm{p},β\mathrm{DF}} (^{188}\mathrm{Bi^{ls}})=5.6(8)×10^3$ s and $T_{1/2\mathrm{p},β\mathrm{DF}} (^{188}\mathrm{Bi^{hs}})=1.7(6)×10^3$ s.

/ Barzakh, A (St. Petersburg, INP) ; Andreyev, A N (JAEA, Ibaraki ; York U., England) ; Raison, C (York U., England) ; Cubiss, J G (York U., England) ; Van Duppen, P (Leuven U.) ; Péru, S (CEA DAM) ; Hilaire, S (CEA DAM) ; Goriely, S (Brussels U., IAA) ; Andel, B (Comenius U.) ; Antalic, S (Comenius U.) et al.
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 nuclear-decay spectroscopy study of the neutron-deficient isotope At196 is reported where an isotopically pure beam was produced using the selective Resonance Ionization Laser Ion Source and On-Line Isotope Mass Separator (CERN). The fine-structure α decay of At196 allowed the low-energy excited states in the daughter nucleus Bi192 to be investigated. [...]

A study of the laser-ionized and mass-separated neutron-deficient isotopes $^{176,177,179}$Au was performed using the Resonance Ionization Laser Ion Source and the Windmill detection setup at ISOLDE, CERN. New and improved data on complex fine-structure α decays of the three isotopes were deduced, providing insight into the low-lying levels in the daughter nuclei $^{172,173,175}$Ir. [...]
