“…5). As the hfs of astatine isotopes have not been measured prior to this study, there are no high-resolution data available to fix the ratios of the hyperfine constants for the upper and lower electronic levels of the transition used in this study (as, for example, was done in the case of thallium nuclei [31]). Instead, the well-resolved hfs spectra for the 197 At m (I π = 1/2 + ) and the hfs spectra for 205 At (I π = 9/2 − ) obtained with high statistics were used in order to fix these ratios for all other isotopes of astatine.…”

Experimental study of isomeric intruder 12+ states in At197,203

A newly observed isomeric intruder 1 /2 + state [T1 /2 = 3.5(6) ms] is identified in 203 At using a gas-filled recoil separator and fusion-evaporation reactions. The isomer is depopulated through a cascade of E3 and mixed M1/E2 transitions to the 9 /2 − ground state, and it is suggested to originate from the π (s1 /2 ) −1 configuration. In addition, the structures above the 1 /2 + state in 203 At and 197 At are studied using in-beam γ -ray spectroscopy, recoil-decay tagging, and recoil-isomer decay tagging methods. The 1 /2 + state is fed from 3 /2 + and 5 /2 + states, and the origin of these states are discussed.

“…In-source laser spectroscopy studies on the neutrondeficient 193,195,197 Bi isotopes support the previous suggestions of shape-coexistence between a nearly spherical ground state and a deformed intruder isomer [8]: the relative charge radii of these 83 Bi ground states are identical to those of their corresponding lead isotones, which were found to be spherical [9]. The isomeric π 3s 1/2 intruder states, however, possess a large isomer shift, suggesting that these states are significantly deformed.…”

Quadrupole moment of Fr203

The spectroscopic electric quadrupole moment of the neutron-deficient francium isotope 203 Fr was measured by using high-resolution collinear resonance ionization spectroscopy (CRIS) at the CERN Isotope Separation On-Line Device (ISOLDE) facility. A remeasurement of the 207 Fr quadrupole moment was also performed, resulting in a departure from the established literature value. A sudden increase in magnitude of the 203 Fr quadrupole moment, with respect to the general trend in the region, points to an onset of static deformation at N = 116 in the 87 Fr isotopic chain. Calculation of the static and total deformation parameters show that the increase in static deformation only cannot account for the observed departure of its relative charge radius from the 82 Pb chain.
