Competition between Allowed and First-Forbidden $β$ Decay: The Case of $^{208}$Hg$→^{208}$Tl
/ Carroll, R J (Surrey U.) ; Podolyák, Zs (Surrey U. ; Darmstadt, GSI) ; Berry, T (Surrey U.) ; Grawe, H (Darmstadt, GSI) ; Alexander, T (Surrey U.) ; Andreyev, A N (York U., England ; JAEA, Ibaraki) ; Ansari, S (Cologne U.) ; Borge, M J G (CERN) ; Brunet, M (Surrey U.) ; Creswell, J R (Liverpool U.) et al.
The $β$ decay of $^{208}$Hg into the one-proton hole, one neutron-particle $^{208}_{81}$Tl$_{127}$ nucleus was investigated at CERN-ISOLDE. Shell-model calculations describe well the level scheme deduced, validating the proton-neutron interactions used, with implications for the whole of the N>126, Z<82 quadrant of neutron-rich nuclei.

Octupole states in $^{207}$Tl studied through $β$ decay
/ Berry, T A (Surrey U.) ; Podolyák, Zs (Surrey U.) ; Carroll, R J (Surrey U.) ; Lică, R (CERN ; Bucharest, IFIN-HH) ; Brown, B A (Michigan State U.) ; Grawe, H (Darmstadt, GSI) ; Sotty, Ch (Bucharest, IFIN-HH ; Leuven U.) ; Timofeyuk, N K (Surrey U.) ; Alexander, T (Surrey U.) ; Andreyev, A N (York U., England) et al.
The $β$ decay of $^{207}$Hg into the single-proton-hole nucleus $^{207}$Tl has been studied through $γ$-ray spectroscopy at the ISOLDE Decay Station (IDS) with the aim of identifying states resulting from coupling of the $πs^{−1}_{1/2}, πd^{−1}_{3/2},$ and $πh^{−1}_{11/2}$ shell model orbitals to the collective octupole vibration. Twenty-two states were observed lying between 2.6 and 4.0 MeV, eleven of which were observed for the first time, and 78 new transitions were placed. [...]

The β decay of the N=Z nucleus $^{72}$Kr has been studied with the total absorption spectroscopy technique at ISOLDE (CERN). A total B(GT)=0.79(4)$g_{A}^{2}/$4π has been found up to an excitation energy of 2.7 MeV. [...]

Investigation of the $\Delta n = 0$ selection rule in Gamow-Teller transitions: The $\beta$-decay of $^{207}$Hg
/ Berry, T A (Surrey U.) ; Podolyák, Zs (Surrey U.) ; Carroll, R J (Surrey U.) ; Lică, R (CERN ; Bucharest, IFIN-HH) ; Grawe, H ; Timofeyuk, N K (Surrey U.) ; Alexander, T (Surrey U.) ; Andreyev, A N (York U., England) ; Ansari, S (Cologne U.) ; Borge, M J G (CERN ; Madrid, Inst. Estructura Materia) et al.
Gamow-Teller $\beta$ decay is forbidden if the number of nodes in the radial wave functions of the initial and final states is different. This $\Delta n=0$ requirement plays a major role in the $\beta$ decay of heavy neutron-rich nuclei, affecting the nucleosynthesis through the increased half-lives of nuclei on the astrophysical $r$-process pathway below both $Z=50$ (for $N>82$ ) and $Z=82$ (for $N>126$).
