The first and only attempt to synthesize [[unbihexium|element 126]] (unbihexium), which was unsuccessful, was performed in 1971 at [[CERN]] (European Organization for Nuclear Research) by René Bimbot and John M. Alexander<!--don't link; the article titled "John M. Alexander" goes to a different John M. Alexander--> using the hot fusion reaction:<ref name="emsley"/>

:{{nuclide|thorium|232}} + {{nuclide|krypton|84}} → <sup>316</sup>126* → no atoms

[[decay energy|High-energy]] (13–15&nbsp;[[MeV]]) [[alpha particles]] were observed and taken as possible evidence for the synthesis of element 126. Subsequent unsuccessful experiments with higher sensitivity suggest that the 10&nbsp;[[barn (unit)|mb]] sensitivity of this experiment was too low; hence, the formation of element 126 nuclei in this reaction is highly unlikely.<ref name=Transuraniumppl>{{cite book|last1=Hoffman|first1=D.C |last2=Ghiorso|first2=A.|last3=Seaborg|first3=G.T.|title=The Transuranium People: The Inside Story |publisher=Imperial College Press|date=2000|isbn=978-1-86094-087-3}}</ref>
