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.

/ Valiente-Dobón, J.J. (INFN, Legnaro) ; Gottardo, A. (INFN, Legnaro) ; Benzoni, G. (INFN, Milan) ; Gadea, A. (Valencia U., IFIC) ; Lunardi, S. (Padua U. ; INFN, Padua) ; Algora, A.

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 $J=0$.

New spectroscopic information on $^{211,213}\mathrm{Tl}$: A changing structure beyond the $N=126$ shell closure
/ 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 $^{209}\mathrm{Tl}$. [...]

Lifetimes and shape-coexisting states of $^{99}Zr$
/ Spagnoletti, P (West Scotland U.) ; Simpson, G (LPSC, Grenoble) ; Kisyov, S (Bucharest, IFIN-HH) ; Bucurescu, D (Bucharest, IFIN-HH) ; Régis, J M (Cologne U.) ; Saed-Samii, N (Cologne U.) ; Blanc, A (Laue-Langevin Inst.) ; Jentschel, M (Laue-Langevin Inst.) ; Köster, U (Laue-Langevin Inst.) ; Mutti, P (Laue-Langevin Inst.) et al.
Lifetimes of intermediate-spin states in two rotational bands of $^{99}Zr$ have been measured. These states were populated following the neutron-induced fission of $^{235}U$ at the PF1B beamline of the Institut Laue-Langevin, Grenoble, during the EXILL-FATIMA campaign. [...]

Normal and intruder configurations in $^{34}$Si populated in the $\beta^-$ decay of $^{34}$Mg and $^{34}$Al
/ IDS Collaboration
The structure of $^{34}$Si was studied through $\gamma$ spectroscopy separately in the $\beta^-$ decays of $^{34}$Mg and $^{34}$Al at the ISOLDE facility of CERN. Different configurations in $^{34}$Si were populated independently from the two recently identified $\beta$-decaying states in $^{34}$Al having spin-parity assignments $J^\pi = 4^-$ dominated by the normal configuration $\pi (d_{5/2})^{-1} \otimes \nu (f_{7/2})$ and $J^\pi = 1^+$ by the intruder configuration $\pi (d_{5/2})^{-1} \otimes \nu (d_{3/2})^{-1}(f_{7/2})^{2}$.

Multinucleon transfer processes in the $^{197}$ Au+$^{130}$Te reaction studied with a high-resolution kinematic coincidence
/ Galtarossa, F (INFN, Legnaro ; Ferrara U.) ; Corradi, L (INFN, Legnaro) ; Szilner, S (Boskovic Inst., Zagreb) ; Fioretto, E (INFN, Legnaro) ; Pollarolo, G (Turin U. ; INFN, Turin) ; Mijatovic, T (Boskovic Inst., Zagreb) ; Montanari, D (Padua U. ; INFN, Padua) ; Ackermann, D (GANIL ; Ciril-Lab. Mixte CEA-CNRS) ; Bourgin, D ; Courtin, S et al.
Multinucleon transfer processes in the $^{197}$Au+$^{130}$Te at E$_{lab}$ =1.07 GeV system were studied with the PRISMA magnetic spectrometer in coincidence with an ancillary particle detector. For neutron transfer channels we extracted total cross sections and compared them with calculations performed with the GRAZING code. [...]

EXILL—a high-efficiency, high-resolution setup for $\gamma$-spectroscopy at an intense cold neutron beam facility
/ Jentschel, M (Laue-Langevin Inst.) ; Blanc, A (Laue-Langevin Inst.) ; de France, G (GANIL) ; Köster, U (Laue-Langevin Inst.) ; Leoni, S (Milan U.) ; Mutti, P (Laue-Langevin Inst.) ; Simpson, G (LPSC, Grenoble) ; Soldner, T (Laue-Langevin Inst.) ; Ur, C (Padua U. ; Bucharest, IFIN-HH) ; Urban, W (Laue-Langevin Inst. ; Warsaw U.) et al.
In the EXILL campaign a highly efficient array of high purity germanium (HPGe) detectors was operated at the cold neutron beam facility PF1B of the Institut Laue-Langevin (ILL) to carry out nuclear structure studies, via measurements of γ-rays following neutron-induced capture and fission reactions. The setup consisted of a collimation system producing a pencil beam with a thermal capture equivalent flux of about 10(8) n s(−)(1)cm(−)(2) at the target position and negligible neutron halo. [...]

/ Lică, R (CERN) ; Rotaru, F ; Negoită, F ; Grévy, S ; Mărginean, N ; Desagne, Ph ; Stora, T (CERN) ; Borcea, C ; Borcea, R ; Călinescu, S et al.
The results of the IS530 experiment at ISOLDE revealed new information concerning several nuclei close to the N ≈ 20 'Island of Inversion' - 34Mg, 34Al, 34Si. The half-life of 34Mgwas found to be three times larger than the adopted value (63(1) ms instead of 20(10) ms). [...]
