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.

Low-spin states in $^{80}$Ge populated in the $\beta$ decay of the $^{80}$Ga $3^-$ isomer

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. [...]

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 $\pi (d_{5/2})^{-1} \otimes \nu (d_{3/2})^{-1}(f_{7/2})^{2}$.

The LHCb Online system in 2020: trigger-free read-out with (almost exclusively) off-the-shelf hardware
/ Colombo, T (CERN) ; Amihalachioaei, A (CERN ; Gh. Asachi Tech. U., Iasi) ; Arnaud, K (Marseille, CPPM) ; Alessio, F (CERN) ; Brarda, L (CERN) ; Cachemiche, J P (Marseille, CPPM) ; Cámpora, D (CERN ; Seville U.) ; Cap, S (Annecy, LAPP) ; Cardoso, L (CERN) ; Cindolo, F (INFN, Bologna ; U. Bologna, DIFA) et al.
The LHCb experiment at CERN has decided to optimise its physics reach by removing the first level hardware trigger for 2020 and beyond. In addition to requiring fully redesigned front-end electronics this design creates interesting challenges for the data-acquisition and the rest of the online computing system. [...]

Measurement of $^{73}$Ge($n,γ$) cross sections and implications for stellar nucleosynthesis
/ n_TOF Collaboration
$^{73}$Ge($n,γ$) cross sections were measured at the neutron time-of-flight facility n_TOF at CERN up to neutron energies of 300 keV, providing for the first time experimental data above 8 keV. Results indicate that the stellar cross section at kT = 30 keV is 1.5 to 1.7 times higher than most theoretical predictions. [...]

The measurement programme at the neutron time-of-flight facility n_TOF at CERN

/n_TOF
Neutron-induced reaction cross sections are important for a wide variety of research fields ranging from the study of nuclear level densities, nucleosynthesis to applications of nuclear technology like design, and criticality and safety assessment of existing and future nuclear reactors, radiation dosimetry, medical applications, nuclear waste transmutation, accelerator-driven systems and fuel cycle investigations. Simulations and calculations of nuclear technology applications largely rely on evaluated nuclear data libraries. [...]

/n_TOF
The n_TOF neutron time-of-flight facility at CERN is used for high quality nuclear data measurements from thermal energy up to hundreds of MeV. In line with the CERN open data policy, the n_TOF Collaboration takes actions to preserve its unique data, facilitate access to them in standardised format, and allow their re-use by a wide community in the fields of nuclear physics, nuclear astrophysics and various nuclear technologies.

Measurement of the $^{240} \text{Pu(n,f)}$ cross-section at the CERN n_TOF facility: First results from experimental area II (EAR-2)
/ Stamatopoulos, A (Natl. Tech. U., Athens) ; Tsinganis, A (Natl. Tech. U., Athens ; CERN) ; Colonna, N ; Vlastou, R ; Kokkoris, M ; Schillebeeckx, P ; Plompen, A ; Heyse, J ; Žugec, P ; Barbagallo, M et al.
The accurate knowledge of the neutron-induced fission cross-sections of actinides and other isotopes involved in the nuclear fuel cycle is essential for the design of advanced nuclear systems, such as Generation-IV nuclear reactors. Such experimental data can also provide the necessary feedback for the adjustment of nuclear model parameters used in the evaluation process, resulting in the further development of nuclear fission models.
