Abstract. The feasibility of measuring g-factors using the TDPAD method applied to high-energy, heavy fragmentation products is explored. The 2623 keV I π = 12 + isomer in 192 Pb with τ = 1.57 μs has been produced using the fragmentation of a 1 A GeV 238 U beam. The results presented demonstrate for the first time that such heavy nuclei produced in a fragmentation reaction with a relativistic beam are sufficiently well spin-aligned. Moreover, the rather large value of the alignment, 28(10)% of the maximum possible, is preserved during the separation process allowing the determination of magnetic moments. The measured values of the lifetime, τ = 1.54(9) μs, and the g-factor, g = −0. 175(20), agree with the results of previous investigations using fusion-evaporation reactions.

“…This level of electron energy resolution was used to select delayed internal conversion electron lines following decays that were observed in other FRS settings from the same experiment (for example, in the internal conversion decay of a long-lived isomer in 205 Au [33]). For the logarithmic portion of the preamplifier energy response, simulated signals from a pulser were used for the initial energy calibration, which was then checked by comparing the experimental data to simulations from the LISE3 code [34,35].…”

The low-lying structure of 188,190,192 W has been studied following β decays of the neutron-rich mother nuclei 188,190,192 Ta produced following the projectile fragmentation of a 1-GeV-per-nucleon 208 Pb primary beam on a natural beryllium target at the GSI Fragment Separator. The β-decay half-lives of 188 Ta, 190 Ta, and 192 Ta have been measured, with γ -ray decays of low-lying states in their respective W daughter nuclei, using heavy-ion β-γ correlations and a position-sensitive silicon detector setup. The data provide information on the low-lying excited states in 188 W, 190 W, and 192 W, which highlight a change in nuclear shape at 190 W compared with that of lighter W isotopes. This evolution of ground-state structure along the W isotopic chain is discussed as evidence for a possible proton subshell effect for the A ∼ 190 region and is consistent with maximization of the γ -softness of the nuclear potential around N ∼ 116.
