Charge radii of thallium isotopes near the N=126 shell closure / IDS Collaboration
The changes in the mean-squared charge radius of Tlg209 (N=128) and Tlm207 (N=126) relative to Tl205 have been measured for the first time using the in-source laser resonance-ionization spectroscopy technique with the Laser Ion Source and Trap (LIST) at ISOLDE (CERN). The application of the LIST suppresses the dominant background from isobaric francium isotopes and allows access to thallium nuclides with A⩾207. [...]

Search for isospin-symmetry breaking in the $A=62$ isovector triplet / Mihai, R E (Bucharest, IFIN-HH) ; Mare, A S (Bucharest, IFIN-HH ; Bucharest U.) ; Mărginean, N (Bucharest, IFIN-HH) ; Petrovici, A (Bucharest, IFIN-HH ; Bucharest U.) ; Andrei, O (Bucharest, IFIN-HH) ; Boromiza, M (Bucharest, IFIN-HH) ; Bucurescu, D (Bucharest, IFIN-HH) ; Căta-Danil, G (Bucharest, IFIN-HH) ; Clisu, C (Bucharest, IFIN-HH) ; Costache, C (Bucharest, IFIN-HH) et al.
The assignment of the first $2^+$ state in $^{62}$Ga has long been debated, due to its implications in triplet energy difference systematics in this mass region. An experiment has been performed at the IFIN-HH 9-MV Tandem accelerator using the ROSPHERE array in a mixed configuration of LaBr$_3$(Ce) and HPGe detectors, as well as an additional array of liquid scintillator neutron detectors.

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. [...]

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 $N>126$).
