“…8 as a gap between N = 50 and N = 52. In addition to the neutrondeficient data described in this work, Penning trap data from JYFLTRAP [49,109,110] and ISOLTRAP [111] contribute to delineate the position of the shell gap on the neutron-rich side. A minimum in the shell-gap energy was observed for Z = 32 in Ref.…”

The masses of very neutron-deficient nuclides close to the astrophysical rp-and νp-process paths have been determined with the Penning trap facilities JYFLTRAP at JYFL/Jyväskylä and SHIP-TRAP at GSI/Darmstadt. Isotopes from yttrium (Z = 39) to palladium (Z = 46) have been produced in heavy-ion fusion-evaporation reactions. In total 21 nuclides were studied and almost half of the mass values were experimentally determined for the first time:88 Tc,

“…On the other hand, in laser spectroscopy experiments the focus is aimed at measuring nuclear spins, magnetic dipole moments, spectroscopic quadrupole moments, and mean-square charge radii from isotopic shifts. Considerable progress has been achieved in recent years (for a review, see [8] and references therein), and the mass region studied in this work has received special attention [13,[21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36].…”

Shape evolution in yttrium and niobium neutron-rich isotopes

The isotopic evolution of the ground-state nuclear shapes and the systematics of one-quasiproton configurations are studied in neutron-rich odd-A yttrium and niobium isotopes. We use a self-consistent Hartree-FockBogoliubov formalism based on the Gogny energy density functional with two parametrizations, D1S and D1M. The equal-filling approximation is used to describe odd-A nuclei preserving both axial and time-reversal symmetries. Shape-transition signatures are identified in the N = 60 isotopes in both the charge radii and spin parities of the ground states. These signatures are a common characteristic for nuclei in the whole mass region. The nuclear deformation and shape coexistence inherent to this mass region are shown to play a relevant role in the understanding of the spectroscopic features of the ground and low-lying one-quasiproton states. Finally, a global picture of the neutron-rich A ∼ 100 mass region from krypton up to molybdenum isotopes is illustrated with the systematics of the nuclear charge radii isotopic shifts.

“…A set of frequency ratios ν c,ref /ν c,meas and the atomic mass of the reference isotope were then used to calculate the atomic mass for each isotope of interest. The experimental setup for precision mass measurements of neutron-rich fission fragments and the TOF-ICR technique are described in more detail in [11][12][13].…”

The JYFLTRAP double Penning trap setup at the University of Jyväskylä, Finland has been used to perform a wide range of studies related to neutron-rich fission fragments that can be produced with the Ion Guide Isotope Separator OnLine (IGISOL) method. Experimental results from high-precision mass measurements and decay-spectroscopy measurements have allowed us to investigate the nuclear structure of exotic neutron-rich nuclei.
