“…[2] Skalski et al pointed to strong shape variations due to the predicted coexistence of prolate and oblate potential minima and a γ softness expected in Mo-Pd nuclei. Many examples of these phenomena have been observed experimentally in the 100 < A < 120 region, especially effects related to γ softness and triaxiality in neutron-rich Mo-Pd isotopes [4][5][6][7][8][9][10][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29].…”

Monoisotopic samples of exotic, neutron-rich 117 Rh nuclei, produced in the proton-induced fission of 238 U and separated using the IGISOL mass separator coupled to the JYFLTRAP Penning trap, were used to perform β and γ coincidence spectroscopy of 117 Pd. The spin parity of the ground state of 117 Pd was determined to be 1/2 + and the 19.1 ms isomer at 203.2 keV was assigned a spin-parity 7/2 − . The 117 Rh β − -decay scheme was considerably extended, and various sequences of the levels were interpreted as resulting from the prolate, oblate, and triaxial nuclear shapes. Some of the β − decays were considered as the allowed Gamow-Teller transitions. The experimental distribution of Gamow-Teller strength is discussed.

The excited levels of 115 Ag have been studied via the beta decay of 115 Pd and 115 Pd m . The beta-decay schemes for both states have been considerably extended, especially the scheme following the decay of 115 Pd m which was practically unknown before this work. Transition intensities and log 10 f t values are reported, which have been missing in the literature. A set of levels around 2 MeV has been found to be strongly populated by the beta decay of the ground state of 115 Pd and is suggested to have a three-quasiparticle nature. The properties of excited levels have been compared with the level systematics of lighter neutron-rich silver isotopes, and new spin assignments as well as identification of Nilsson states in 115 Ag have been made.

“…As in the experiment, 2-keV 213 Ra 2+ ions in the ground state were sent at a rate of 2.5 Hz towards the DSSSD such that (1) the observed beam profile, i.e., the DSSSD hit pattern of subsequent 213 Ra α decays, reproduces the experimentally observed one, (2) 213 Ra and its daughter activity is built up as in the real experiment, and (3) the statistics of experiment and simulation match.…”

“…More recently, the JYFLTRAP system at the University of Jyväskylä was employed in conjunction with a movable-tape station for selective βγ (γ )-decay studies of neutron-rich Zr, Ru, and Tc isotopes [2][3][4]. In the meantime similar schemes were successfully employed at ISOLDE/CERN with decay stations positioned either behind ISOLTRAP's precision Penning trap [5,6] or its multireflection time-of-flight component [7].…”

The Universal Linear Accelerator (UNILAC) at GSI Darmstadt provided a 48 Ca beam impinging on a thin 170 Er target foil. Subsequent to velocity filtering of reaction products in the Separator for Heavy Ion reaction Products (SHIP), the nuclear ground state of the 5n evaporation channel 213 Ra was mass-selected in SHIPTRAP, and the 213 Ra ions were finally transferred into an array of silicon strip detectors surrounded by large composite germanium detectors. Based on comprehensive GEANT4 simulations and supported by theoretical calculations, the spectroscopic results call for a revision of the decay path of 213 Ra, thereby exemplifying the potential of a combination of a mass-selective Penning trap device with a dedicated nuclear decay station and contemporary GEANT4 simulations.
