TL;DR: Direct mass measurements of trans-uranium nuclides, located at the farthest tip of the actinide species on the proton number–neutron number diagram, represent the gateway to the predicted island of stability and advance direct mass measurements by ten atomic numbers with no loss in accuracy.
Journal ArticleDOI
ISOLTRAP: An on-line Penning trap for mass spectrometry on short-lived nuclides
Manas Mukherjee,Dietrich Beck,Klaus Blaum,Georg Bollen,Jens Dilling,Sebastian George,F. Herfurth,Alexander Herlert,Alban Kellerbauer,H.-J. Kluge,Stefan Schwarz,Lutz Schweikhard,C. Yazidjian +12 more
TL;DR: ISOLTRAP as discussed by the authors is a Penning trap mass spectrometer for high-precision mass measurements on short-lived nuclides installed at the on-line isotope separator ISOLDE at CERN.
Journal ArticleDOI
Direct Mapping of Nuclear Shell Effects in the Heaviest Elements
E. Minaya Ramirez,Dieter Ackermann,Klaus Blaum,Michael Block,C. Droese,Ch. E. Düllmann,M. Dworschak,M. Eibach,Sergey Eliseev,E. Haettner,F. Herfurth,F. P. Heßberger,Stefan G. Hofmann,Jens Ketelaer,Gerrit Marx,M. Mazzocco,Dmitrii Nesterenko,Yu. N. Novikov,Wolfgang R. Plaß,Daniel Rodríguez,C. Scheidenberger,Lutz Schweikhard,P. G. Thirolf,Christian Weber +23 more
TL;DR: High-precision mass spectrometry allows the direct measurement of nuclear binding energies and thus the determination of the strength of shell effects, and presents measurements for nobelium and lawrencium isotopes, which also pin down the deformed shell gap at N = 152.
Journal ArticleDOI
Plumbing Neutron Stars to New Depths with the Binding Energy of the Exotic Nuclide Zn 82
Robert Wolf,D. Beck,Klaus Blaum,Ch. Böhm,Ch. Borgmann,M. Breitenfeldt,Nicolas Chamel,S. Goriely,F. Herfurth,Magda Kowalska,Susanne Kreim,Susanne Kreim,D. Lunney,Vladimir Manea,E. Minaya Ramirez,S. Naimi,Dennis Neidherr,Marco Rosenbusch,Lutz Schweikhard,J. Stanja,Frank Wienholtz,Kai Zuber +21 more
TL;DR: With a robust neutron-star model based on nuclear energy-density-functional theory, the general relativistic Tolman-Oppenheimer-Volkoff equations are solved and the composition profile is not only altered but now constrained by experimental data deeper into the crust than before.
Journal ArticleDOI
The Ramsey method in high-precision mass spectrometry with Penning traps: Experimental results
Sebastian George,Klaus Blaum,F. Herfurth,Alexander Herlert,Martin Kretzschmar,Szilard Nagy,Stefan Schwarz,Lutz Schweikhard,C. Yazidjian +8 more
TL;DR: In this paper, a new excitation scheme, Ramsey's method of time-separated oscillatory fields, has been successfully tested with the ISOLTRAP mass spectrometer at ISOLDE/CERN for mass measurements on stable as well as short-lived nuclides.
