$^{208}$Po populated through EC/β$^{+}$ decay / Brunet, M (Surrey U.) ; Berry, T A (Surrey U.) ; Podolyák, Zs (Surrey U.) ; Carroll, R J (Surrey U.) ; Lica, R (CERN ; Bucharest, IFIN-HH) ; Sotty, Ch (Bucharest, IFIN-HH ; Leuven U.) ; Andreyev, A N (York U., England) ; Borge, M J G (CERN) ; Cubiss, J G (CERN ; York U., England) ; Fraile, L M (Madrid U.) et al.
The structure of $^{208}$Po resulting from the EC/β + decay of $^{208}$At was studied at CERN’s ISOLDE Decay Station (IDS). The high statistics afforded by the high yield of $^{208}$At and the high efficiency HPGe clusters at the IDS allowed for greater insight into lower intensity transitions and thus significant expansion of the $^{208}$Po level scheme.

Competition between allowed and first-forbidden $β$ decays of $^{208}$At and expansion of the $^{208}$Po level scheme / Brunet, M (Surrey U.) ; Podolyák, Zs (Surrey U.) ; Berry, T A (Surrey U.) ; Brown, B A (Michigan State U., NSCL) ; Carroll, R J (Surrey U.) ; Lica, R (CERN ; Bucharest, IFIN-HH) ; Sotty, Ch (Bucharest, IFIN-HH ; Leuven U.) ; Andreyev, A N (York U., England ; JAEA, Ibaraki) ; Borge, M J G (CERN) ; Cubiss, J G (CERN ; Madrid U.) et al.
The structure of $^{208}$Po populated through the EC/$β^+$ decay of $^{208}$At is investigated using $γ$-ray spectroscopy at the ISOLDE Decay Station. The presented level scheme contains 27 new excited states and 43 new transitions, as well as a further 50 previously observed $γ$ rays which have been (re)assigned a position. [...]

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. [...]

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 $N>126$).

First Accurate Normalization of the $\beta$-delayed $\alpha$ Decay of $^{16}$N and Implications for the $^{12}$C$(\alpha,\gamma)^{16}$O Astrophysical Reaction Rate / Kirsebom, O.S. (Aarhus U.) ; Tengblad, O. (CSIC, Madrid) ; Lica, R. (CERN ; Bucharest, IFIN-HH) ; Munch, M. (Aarhus U.) ; Riisager, K. (Aarhus U.) ; Fynbo, H.O.U. (Aarhus U.) ; Borge, M.J.G. (CSIC, Madrid ; CERN) ; Madurga, M. (CERN) ; Marroquin, I. (CSIC, Madrid) ; Andreyev, A.N. (York U., England) et al.
The $^{12}\text{C}(\alpha,\gamma){}^{16}\text{O}$ reaction plays a central role in astrophysics, but its cross section at energies relevant for astrophysical applications is only poorly constrained by laboratory data. The reduced $\alpha$ width, $\gamma_{11}$, of the bound $1^-$ level in $^{16}$O is particularly important to determine the cross section. [...]
