Evidence for the formation of sodium hassate(VIII)
- A. von Zweidorf, W. Brüchle, +9 authors N. Wiehl
- Chemistry
- 2004
Summary Hassium, element 108, was produced in the fusion reaction between 26Mg and 248Cm. The hassium recoils were oxidized in-situ to a highly volatile oxide, presumably HsO4, and were transported… Expand
