Chemical investigation of hassium (element 108)
- Ch. E. Düllmann, W. Brüchle, +31 authors P. Zieliński
- Chemistry, Medicine
- Nature
- 22 August 2002
The periodic table provides a classification of the chemical properties of the elements. But for the heaviest elements, the transactinides, this role of the periodic table reaches its limits because… Expand

Abstract
Neutrinos, and in particular their tiny but non-vanishing masses, can be considered one of the doors towards physics beyond the Standard Model. Precision measurements of the kinematics of… Expand
The Electron Capture $$^{163}$$163Ho Experiment ECHo
- L. Gastaldo, K. Blaum, +15 authors M. Wegner
- Physics
- 11 June 2013
The determination of the absolute scale of the neutrino masses is one of the most challenging present questions in particle physics. The most stringent limit, $$m(\bar{\nu }_{\mathrm {e}})<… Expand

A general understanding of the molecular plating process was obtained recently, which serves as a first step towards further improvements of the method aiming, for example, at the production of… Expand
Physical preseparation: A powerful new method for
transactinide chemists
- Ch. E. Düllmann
- 16 February 2007
Abstract.In recent years, the concept of physical preseparation of single atoms was
introduced into the field of transactinide chemistry. In this approach, the
transactinide element of interest is… Expand
