FATIMA (FAst TIMing Array) [1] is the fast-timing detector system for measurements of nuclear lifetimes at the DESPEC (DEcay SPECtroscopy) station [2] of the radioactive beam facility GSI. The array is composed of 36 LaBr$_3$(Ce) scintillator detectors coupled to photomultiplier tubes and the GSI-developed fast-timing data acquisition system TAMEX, making possible lifetime measurements on the...
The FAst TIMing Array (FATIMA) detector system is a key component of the DEcay SPECtroscopy (DESPEC) experiment at the Facility for Antiproton and Ion Research (FAIR). FATIMA currently comprises 36 cylindrical 1.5×2" LaBr3(Ce) detectors, designed for precise measurements of mean lifetimes in the picosecond-to-nanosecond range [1]. These sensitive measurements use the exceptional timing...
ILL operates two user instruments that enable fast timing measurements with nuclides that are either neutron-rich or close to stability.
The LOHENGRIN fission fragment recoil separator provides mass- and energy separated beams of fission products. In particular short-lived (microsecond) isomers or beams of refractory elements that are less suited for ISOL facilities are of interest for decay...
Regions near closed shells in areas of the nuclear chart far from stability are very interesting from the point of view of nuclear structure, since they provide an ideal testing ground to investigate the competition between single particle degrees of freedom and collective effects from many nucleons. This is the case for nuclei near the doubly-magic $^{78}$Ni nucleus, with Z = 28 and N = 50...
The region around N≈60 with Z≤40 has generated considerable interest as it features the most abrupt shape transition known to date in the nuclear chart, when crossing from N=58 to N=60 [1]. This transition is closely linked to shape coexistence [2], a phenomenon where two or more states with different intrinsic shapes coexist within the same nucleus at low excitation energy and within a narrow...
Since N=56 is one of the so-called "octupole magic numbers", $^{96}\mathrm{Zr}$ is expected to show a strong octupole collectivity. According to several experiments carried out about 30 years ago to determine the $B(E3; 0^{+}_1 \rightarrow 3^{-}_1 )$ value, it is one of the largest in the entire nuclear chart. However, the results differ by $30\%$. We therefore carried out an experiment at ILL...
