The discovery of element 111 caps a remarkable season for the Darmstadt lab, which in November found element 110
(SN: 11/26/94, p.
An isotope of element 110
with an atomic weight of 269 made its debut in Germany (146: 356).
Researchers at GSI, the center for heavy ion research in Darmstadt, reported evidence last week of an isotope of element 110
, with an atomic mass of 269.
So far the heaviest element claimed by any researchers in the field is element 110
, which has been the object of experiments by a Dubna group led by Yuri Oganessian.
All elements heavier than uranium that have been found so far are subject to radioactive decay, but there is a strong hope that somewhere above element 110
there is a range of stable or relatively stable elements.
