“…Half of the detectors were used with their BGO anti-Compton suppression shields [26] in place. To suppress the low-energy atomic bremsstrahlung associated with the arrival of the beam [23], all detector faces were covered by Cu and Pb absorbers, each 1 mm thick. This provided a useful γ -ray energy detection range of between ∼140 keV and ∼4 MeV, the upper limit being due to the selected ADC range of the used Euroball VXI cards.…”

New sub-µs isomers have been observed in the neutron-rich Sn isotopes. 125,127,129 Sn nuclei have been produced in a relativistic fission reaction of 238 U on a 9 Be target at 750 A·MeV and by the fragmentation of 136 Xe at 600 A·MeV populating high-spin yrast states. In addition to the already known µs isomers, three new ones with sub-µs half-lives have been observed. These yrast isomers are the high-spin members of the ν(d −1 3/2 h −2 11/2 ) and νh −n 11/2 , seniority v = 3 multiplets leading to isomeric (23/2 + ) and (27/2 − ) states, respectively. Added to the already known 19/2 + µs isomers in this region the current work completes the systematic information of neutron-hole excitations toward the filling of the last h 11/2 orbital at N = 82. The results are discussed in the framework of state-of-the-art shell-model calculations using realistic interactions.

“…The calculations predict a photopeak efficiency for this 1π array of ≈15% for E/A=100 MeV (β=0.43), and an energy resolution better than 1%. In contrast, the full peak efficiency of the 15 cluster detectors of the RISING array in its fast beam configuration [9] is 2.8% for a 1.3 MeV gamma ray emmitted in-flight at E/A=100 MeV.…”

“…Thick targets, of the order of several 100 mg/cm 2 , can be used and relevant cross sections are of the order of 0.1 barn. Such experiments have been already performed at RISING [9] (see figure 2). For example: Coulomb excitation of 54,56,58 Cr nuclei [10], providing B(E2; 2 + → 0 + ) transition strenghts, gave information about the shell evolution around N=34; secondary fragmentation reactions were used to test isospin symmetry at the drip line, by measuring the 2 + excited state in 36 Ca [11].…”

on behalf of the RISING CollaborationSome of the most interesting Nuclear Structure physics cases and phenomena, addressed with experiments made with RISING, are presented and discussed. The RISING array is located at GSI and, since 2003, is active in gamma-spectroscopy experiments for the study of the properties of exotic nuclei. There are several topics which have been experimentally tackled by the RISING collaborations, among them focus is given to the problem of shell quenching and on the collective properties of neutron rich nuclei. Both aspects have an interest which goes beyond nuclear structure as they can affect, for example, stellar nucleosynthesis during the r-process in supernova explosion. In particular, four physics cases will be discussed moving from light to heavy nuclei. The first is connected to the 36 Ca nucleus, interesting for the study of isospin symmetry. The second is the study of the collective properties of 68 Ni and the search of the Pygmy Dipole Resonance and thus the determination of the symmetry energy slope parameter. The third topic is the structure of 130 Cd, a nucleus constituting a waiting point in the r-process. Finally, some preliminary results from an experiment on neutron rich Z~82 isotopes are presented. Some future perspectives in connection with the new PRESPEC international collaboration are also discussed.
