Hochsch.) ; Bemmerer, D (HZDR, Dresden) ; Benouaret, N (Algiers U. Sci. Tech.) ; Beyer, R (HZDR, Dresden) ; Butterling, M (HZDR, Dresden) et al.
The dipole strength of the nuclide $^{66}$Zn was studied in photon-scattering experiments using bremsstrahlung produced with electron beams of energies of 7.5 and 13.4 MeV at the γELBE facility as well as using quasimonoenergetic and linearly polarized photon beams of 30 energies within the range of 4.3 to 9.9 MeV at the HIγS facility. A total of 128 J=1 states were identified, among them 9 with 1$^+$ and 86 with 1$^−$ assignments. [...]

/ 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. [...]

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 $J=0$.

/ Napiralla, P (Darmstadt, Tech. Hochsch. ; Darmstadt, GSI) ; Lettmann, M (Darmstadt, Tech. Hochsch.) ; Stahl, C (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).

Testing ab initio nuclear structure in neutron-rich nuclei: lifetime measurements of second 2$^+$ states in $^{16}$C and $^{20}$O
/ Ciemala, M. (Cracow, INP) ; Ziliani, S. (Milan U. ; INFN, Milan) ; Crespi, F.C.L. (Milan U. ; INFN, Milan) ; Leoni, S. (Milan U. ; INFN, Milan) ; Fornal, B. (Cracow, INP) ; Maj, A. (Cracow, INP) ; Bednarczyk, P. (Cracow, INP) ; Benzoni, G. (INFN, Milan) ; Bracco, A. (Milan U. ; INFN, Milan) ; Boiano, C. (INFN, Milan) et al.
To test the predictive power of ab initio nuclear structure theory, the lifetime of the second 2+ state in neutron-rich 20O, tau(2+_2 ) = 150(+80-30) fs, and an estimate for the lifetime of the second 2+ state in 16C have been obtained, for the first time. The results were achieved via a novel Monte Carlo technique that allowed us to measure nuclear state lifetimes in the tens-to-hundreds femtoseconds range, by analyzing the Doppler-shifted gamma-transition line shapes of products of low-energy transfer and deep-inelastic processes in the reaction 18O (7.0 MeV/u) + 181Ta.

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 . [...]

/ Gottardo, A (INFN, Legnaro ; Padua U.) ; Valiente-Dobón, J J (INFN, Legnaro) ; Benzoni, G (INFN, Milan) ; Morales, A I (INFN, Milan) ; Gadea, A (Valencia U., IFIC) ; Lunardi, S (Padua U. ; INFN, Padua) ; Boutachkov, P (Darmstadt, GSI) ; Bruce, A M (Brighton U.) ; Górska, M (Darmstadt, GSI) ; Grebosz, J (Cracow, INP) et al.
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 $^{209}\mathrm{Tl}$. [...]

Nuclear astrophysics with radioactive ions at FAIR
/ Reifarth, R. ; Altstadt, S. ; Göbel, K. ; Heftrich, T. ; Heil, M. ; Koloczek, A. ; Langer, C. ; Plag, R. ; Pohl, M. ; Sonnabend, K. et al.
The nucleosynthesis of elements beyond iron is dominated by neutron captures in the s and r processes. However, 32 stable, proton-rich isotopes cannot be formed during those processes, because they are shielded from the s-process flow and r-process beta-decay chains. [...]
