Coulomb excitation of Zn74,76
/ ISOLDE Collaboration
The first experiment using radioactive beams post-accelerated by the HIE-ISOLDE facility has enabled to obtain a precise set of B(E2) transition probabilities in neutron-rich Zn74,76 isotopes. The resulting B(E2; 21+→01+) values are consistent with those determined in earlier REX-ISOLDE measurements. [...]

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 $J=0$.

Benchmarking the PreSPEC@GSI experiment for Coulex-multipolarimetry on the $\pi (p_{3/2})\rightarrow \pi (p_{1/2})$ spin-flip transition in $^{85}$Br
/ Napiralla, P (Darmstadt, Tech. Hochsch. ; Darmstadt, GSI) ; Lettmann, M (Darmstadt, Tech. Hochsch.) ; Stahl, C (Darmstadt, Tech. Hochsch.) ; Rainovski, G (Sofiya U.) ; Pietralla, N (Darmstadt, Tech.

A first performance test of the Coulomb excitation multipolarimetry (Coulex-multipolarimetry) method is presented. It is based on a $^{85}\hbox {Br}\,\pi p_{3/2}\rightarrow \pi p_{1/2}$ spin-flip experiment performed as part of the PreSPEC-AGATA campaign at the GSI Helmholtzzentrum für Schwerionenforschung (GSI).

Lab) ; Milne, S A (York U., England) ; Bentley, M A (York U., England) ; Recchia, F (Padua U. ; INFN, Padua) ; Lenzi, S M (Padua U. ; INFN, Padua) ; Rudolph, D (Lund U.) ; Labiche, M (Daresbury) ; Pereira-Lopez, X (York U., England) ; Afara, S (King Saud U.) ; Ameil, F (Darmstadt, GSI) et al.
Electric quadrupole matrix elements, Mp , for the Jπ=2+→0+ , ΔT=0 , T=1 transitions across the A=46 isobaric multiplet 46 Cr- 46 V- 46 Ti have been measured at GSI with the FRS-LYCCA-AGATA setup. This allows direct insight into the isospin purity of the states of interest by testing the linearity of Mp with respect to Tz . [...]

New spectroscopic information on $^{211,213}\mathrm{Tl}$: A changing structure beyond the $N=126$ shell closure

The neutron-rich isotopes $^{211,213}\mathrm{Tl}$, beyond the $N=126$ shell closure, have been studied for the first time in isomer $\gamma$-ray decay, exploiting the fragmentation of a primary uranium beam at the Fragment Separator-Rare Isotopes Investigation at GSI setup. The observed isomeric states in $^{211,213}\mathrm{Tl}$ show a deviation from the seniority-like scheme of $^{209}\mathrm{Tl}$. [...]
