$^{133}$In: A Rosetta Stone for decays of r-process nuclei
/ Xu, Z.Y. (U. Tennessee, Knoxville) ; Madurga, M. (U. Tennessee, Knoxville) ; Grzywacz, R. (U. Tennessee, Knoxville ; Oak Ridge) ; King, T.T. (U. Tennessee, Knoxville ; Oak Ridge) ; Algora, A.

(Bucharest, IFIN-HH ; Leuven U.) et al.
The $\beta$ decays from both the ground state and a long-lived isomer of $^{133}$In were studied at the ISOLDE Decay Station (IDS). With a hybrid detection system sensitive to $\beta$, $\gamma$, and neutron spectroscopy, the comparative partial half-lives (logft) have been measured for all their dominant $\beta$-decay channels for the first time, including a low-energy Gamow-Teller transition and several First-Forbidden (FF) transitions.

Estructura Materia) ; Costache, C. (Bucharest, IFIN-HH) et al.
The decay properties of $^{133}$In were studied in detail at the ISOLDE Decay Station (IDS). The implementation of the Resonance Ionization Laser Ion Source (RILIS) allowed separate measurements of its $9/2^+$ ground state ($^{133g}$In) and $1/2^-$ isomer ($^{133m}$In). [...]

Low-lying electric dipole $γ$-continuum for the unstable $^{62,64}$Fe nuclei: Strength evolution with neutron number
/ Avigo, R (INFN, Milan ; Milan U.) ; Wieland, O (INFN, Milan) ; Bracco, A (INFN, Milan ; Milan U.) ; Camera, F (INFN, Milan ; Milan U.) ; Ameil, F (Darmstadt, GSI) ; Arici, T (Darmstadt, GSI) ; Ataç, A (Royal Inst. Tech., Stockholm) ; Barrientos, D (CERN) ; Bazzacco, D (INFN, Padua) ; Bednarczyk, P (Cracow, INP) et al.
The γ -ray emission from the nuclei $^{62,64}$Fe following Coulomb excitation at bombarding energy of 400-440 AMeV was measured with special focus on E 1 transitions in the energy region 4-8 MeV. The unstable neutron-rich nuclei $^{62,64}$Fe were produced at the FAIR-GSI laboratories and selected with the FRS spectrometer. [...]

Manifestation of the Berry phase in the atomic nucleus $^{213}$Pb

The neutron-rich $^{213}$Pb isotope was produced in the fragmentation of a primary 1 GeV $A$ $^{238}$U beam, separated in FRS in mass and atomic number, and then implanted for isomer decay $\gamma$-ray spectroscopy with the RISING setup at GSI. A newly observed isomer and its measured decay properties indicate that states in $^{213}$Pb are characterized by the seniority quantum number that counts the nucleons not in pairs coupled to angular momentum $J=0$.
