Times Cited Count:25 Percentile:79.15(Astronomy & Astrophysics)The low-lying structures of the self-conjugate () nuclei Nb and Tc have been investigated using isomeric-decay spectroscopy following the projectile fragmentation of a Ag beam. These represent the heaviest odd-odd nuclei in which internal decays have been identified to date. The resulting level schemes shed light on the shape evolution along the line between the doubly-magic systems Ni and Sn and support a preference for states in odd-odd nuclei at low excitation energies associated with a neutron-proton pairing gap. Comparison with Projected Shell Model calculations suggests that the decay in Nb may be interpreted as an isospin-changing isomer.

Times Cited Count:11 Percentile:55.77(Physics, Multidisciplinary)Relativistic energy projectile fragmentation of Pb has been used to produce a range of exotic nuclei. The nuclei of interest were studied by detecting delayed rays following the decay of isomeric states. Experimental information on the excited states of the neutron-rich Pt N=126 nucleus, following internal decay of two isomeric states, was obtained for the first time. In addition, decays from the previously reported isomeric and states in Tb and Gd, respectively, have been observed. These isomeric decays represent the highest discrete states observed to date following a prejectile fragmentation reaction, and opens up the possibilty of doing "high-spin physics" using this technique.

Times Cited Count:92 Percentile:98.43(Instruments & Instrumentation)The first results from the stopped beam RISING experimental campaign performed at the GSI laboratory in Darmstadt, Germany, are presented. RISING constitutes a major new experimental program in European nuclear structure physics research aimed at using relativistic energy (typically around 1 GeV per nucleon) projectile fragmentation reactions to populate nuclei with highly exotic proton-to-neutron ratios compared to the line of beta stability. In its high-efficiency stopped beam configuration, the RISING -ray spectrometer consists of 105 individual germanium crystals which view a focal plane in which the exotic nuclei are brought to rest. Here, decays from metastable states with half-lives in the nano to milliseconds range can be observed. Results of initial commissioning experiments are also shown and details of the planned future experimental program are given.

The nuclei of interest were studied by detecting delayed rays following the decay of isomeric states. Experimental information on the excited states of the neutron-rich Pt N=126 nucleus, following internal decay of two isomeric states, was obtained for the first time. Raw experimental data and shell-model calculations are presented.

Times Cited Count:32 Percentile:86.59(Astronomy & Astrophysics)The first excited state of Ca was measured at GSI for the first time. The measured energy is found to be 3015(16) keV, which is lower than its mirror nucleus S by as large as 276 keV. The structure of those nuclei is studied by the shell model. It is found that those nuclei can be well described by the valence space. The large energy shift between them is caused by the Thomas-Ehrman effect. We presented that the energy shift in the shell region can be explained by the shell model with a phenomenological treatment of the Thomas-Ehrman effect.
