The JYFLTRAP double Penning trap at the Ion Guide Isotope Separator On-Line (IGISOL) facility has been used to measure the atomic masses of 13 neutron-rich rare-earth isotopes. Eight of the nuclides, $^{161}$Pm, $^{163}$Sm, $^{164,165}$Eu, $^{167}$Gd, and $^{165,167,168}$Tb, were measured for the first time. [...]

Low-spin states in $^{80}$Ge populated in the $\beta$ decay of the $^{80}$Ga $3^-$ isomer
/ Sekal, S (Algiers U. Sci. Tech. ; CERN) ; Fraile, L M (Madrid U.) ; Lică, R (CERN ; Bucharest, IFIN-HH) ; Borge, M J G (Madrid, Inst. Estructura Materia) ; Walters, W B (Maryland U., Dept.

Lab.) et al.
The structure of
$^{80}$Ge has been investigated at the ISOLDE facility at CERN. A previous study reported for the first time a low-lying $0^+_2$ intruder state at 639 keV, based on the coincidence with a previously unobserved 1764-keV $γ$ ray, and suggested it as evidence for shape coexistence in $^{80}$Ge. [...]

Search for the $^{73}\mathrm{Ga}$ ground-state doublet splitting in the $\beta$ decay of $^{73}\mathrm{Zn}$
/ Vedia, V (UCM, Madrid, Dept. Phys.) ; Paziy, V (UCM, Madrid, Dept. Phys.) ; Fraile, L M (UCM, Madrid, Dept. Phys.) ; Mach, H (UCM, Madrid, Dept. Phys. ; NCBJ, Swierk) ; Walters, W B (Maryland U., Dept. Chem.) ; Aprahamian, A (Notre Dame U.) ; Bernards, C (Cologne U. ; Yale U. (main)) ; Briz, J A (Madrid, Inst. Estructura Materia) ; Bucher, B (Notre Dame U. ; LLNL, Livermore) ; Chiara, C J (Maryland U., Dept. Chem. ; Argonne, PHY) et al.
The existence of two close-lying nuclear states in $^{73}$Ga has recently been experimentally determined: a 1/2$^−$ spin-parity for the ground state was measured in a laser spectroscopy experiment, while a J$^{\pi} = 3/2^−$ level was observed in transfer reactions. This scenario is supported by Coulomb excitation studies, which set a limit for the energy splitting of 0.8 keV. [...]

Search for shape-coexisting 0$^+$ states in $^{66}$Ni from lifetime measurements

The lifetime of the 0$_3^+$ state in $^{66}$Ni, two neutrons below the $N=40$ subshell gap, has been measured. The transition $B(E2;0_3^+ \rightarrow 2_1^+)$ is one of the most hindered E2 transitions in the Ni isotopic chain and it implies that, unlike $^{68}$Ni, there is a spherical structure at low excitation energy.

Fast-timing study in the 78Ni region: $\beta$-Decay of 81Zn

The neutron-rich nucleus $^{81}$Ga was populated from the $\beta$-decay of $^{81}$Zn produced at the ISOLDE (CERN) facility. The analysis of $\beta$-gated $\gamma$-ray singles and $\gamma-\gamma$ coincidences permits to extend significantly the level scheme of $^{81}$Ga as well as to provide a new half-life for $^{81}$Zn.
