Laser Spectroscopy of Thulium Isotopes Near the Shell Closure: Nuclear Moment and Charge Radius of
Jana Weyrich, Kenneth van Beek, Harshithbabu +34
We report on resonance ionization laser spectroscopy measurements performed on both neutron-deficient and neutron-rich thulium () isotopes. Isotope shifts were d…
Stepping into the Sea of Instability: The New Sub-us Superheavy Nucleus 252Rf
J. Khuyagbaatar, P. Mosat, J. Ballof +14
We report the discovery of the new isotope Rf. With its extremely short half-life of ~ns, it expands the range of half-lives of the known superheavy nuclei…
K Isomers in Transuranium Nuclei
Fritz Peter Heßberger
K isomers in transuranium nuclei have become a most interesting subject in nuclear structure investigation in many laboratories within the recent twenty years. In this paper an ove…
Evaporation Residue Production in Complete and Incomplete Fusion Reactions of Ne-20 with Au-197 and Ho-165 at E = 14.9 x AMeV
Fritz Peter Heßberger
Velocity distributions of heavy residues (A_Res > A_Tar), produced in irradiations of Au-197 and Ho-165 with Ne-20 at bombarding energies of E = 208 MeV, have been measured at the…
Some Aspects on Identification, Decay Properties and Nuclear Structure of the Heaviest Nuclei
Fritz Peter Hessberger
Synthesis of new elements at the upper border of the charts of nuclei and investigation of their decay properties and nuclear structure has been one of the main research topics in…
Some remarks on the discovery of Md-244
F. P. Hessberger, M. Block, Ch. E. Duellmann +3
In two recent papers by Pore et al. and Khuyagbaatar et al. discovery of the new isotope Md-244 was reported. The decay data, however, are conflicting. While Pore et al. report two…
Recoil-alpha-fission and recoil-alpha-alpha-fission events observed in the reaction Ca-48 + Am-243
U. Forsberg, D. Rudolph, L. -L. Andersson +51
Products of the fusion-evaporation reaction Ca-48 + Am-243 were studied with the TASISpec set-up at the gas-filled separator TASCA at the GSI Helmholtzzentrum für Schwerionenforsch…
Direct mapping of nuclear shell effects in the heaviest elements
E. Minaya Ramirez, D. Ackermann, K. Blaum +21
Quantum-mechanical shell effects are expected to strongly enhance nuclear binding on an "island of stability" of superheavy elements. The predicted center at proton number $Z=114,1…
Mass measurements of very neutron-deficient Mo and Tc isotopes and their impact on rp process nucleosynthesis
E. Haettner, D. Ackermann, G. Audi +25
The masses of ten proton-rich nuclides, including the N=Z+1 nuclides 85-Mo and 87-Tc, were measured with the Penning trap mass spectrometer SHIPTRAP. Compared to the Atomic Mass Ev…
Mass measurements in the vicinity of the rp-process and the nu p-process paths with JYFLTRAP and SHIPTRAP
C. Weber, V. -V. Elomaa, R. Ferrer +42
The masses of very neutron-deficient nuclides close to the astrophysical rp- and nu p-process paths have been determined with the Penning trap facilities JYFLTRAP at JYFL/Jyväskylä…
Direct mass measurements beyond the proton drip-line
C. Rauth, D. Ackermann, K. Blaum +24
First on-line mass measurements were performed at the SHIPTRAP Penning trap mass spectrometer. The masses of 18 neutron-deficient isotopes in the terbium-to-thulium region produced…
