Chemical characterization of bohrium (element 107)
- R. Eichler, W. Brüchle, +23 authors A. Yakushev
- Physics, Medicine
- Nature
- 7 September 2000
The arrangement of the chemical elements in the periodic table highlights resemblances in chemical properties, which reflect the elements’ electronic structure. For the heaviest elements, however,… Expand
Evidence for relativistic effects in the chemistry of element 104

- J. Dvorák, W. Brüchle, +22 authors A. Yeremin
- Materials Science, Medicine
- Physical review letters
- 4 April 2008
The analysis of a large body of heavy ion fusion reaction data with medium-heavy projectiles (6 < or = Z < or = 18) and actinide targets suggests a disappearance of the 3n exit channel with… Expand
Doubly magic nucleus (108)(270)Hs162.
- J. Dvorák, W. Brüchle, +21 authors A. Yeremin
- Physics, Medicine
- Physical review letters
- 18 April 2006
Theoretical calculations predict 270Hs (Z=108, N=162) to be a doubly magic deformed nucleus, decaying mainly by alpha-particle emission. In this work, based on a rapid chemical isolation of Hs… Expand
