- Medicine, Physics
- Physical review letters
- 10 September 2013
A high-resolution α, x-ray, and γ-ray coincidence spectroscopy experiment was conducted at the GSI Helmholtzzentrum für Schwerionenforschung. Thirty correlated α-decay chains were detected following… Expand
Probing Sizes and Shapes of Nobelium Isotopes by Laser Spectroscopy.
- S. Raeder, D. Ackermann, +35 authors A. Yakushev
- Physics, Medicine
- Physical review letters
- 8 June 2018
Until recently, ground-state nuclear moments of the heaviest nuclei could only be inferred from nuclear spectroscopy, where model assumptions are required. Laser spectroscopy in combination with… Expand
Superheavy element flerovium (element 114) is a volatile metal.
- A. Yakushev, Jacklyn M. Gates, +41 authors N. Wiehl
- Physics, Medicine
- Inorganic chemistry
- 23 January 2014
The electron shell structure of superheavy elements, i.e., elements with atomic number Z ≥ 104, is influenced by strong relativistic effects caused by the high Z. Early atomic calculations on element… Expand
Production of intense 48Ca ion beam at the U-400 cyclotron
- V. B. Kutner, S. Bogomolov, +5 authors N. Yazvitsky
- Physics
- 4 February 2000
Production of the intense accelerated 48Ca ion beam is the key problem in the experiments on synthesizing of new heavy nuclei. For this purpose an axial injection system with the electron cyclotron… Expand
Decomposition studies of group 6 hexacarbonyl complexes. Part 1: Production and decomposition of Mo(CO)6 and W(CO)6
- I. Usoltsev, R. Eichler, +42 authors Z. Qin
- Chemistry
- 28 March 2016
Abstract Chemical studies of superheavy elements require fast and efficient techniques, due to short half-lives and low production rates of the investigated nuclides. Here, we advocate for using a… Expand
