Aside from the fact that this could be attempted humor … published by two 
Iranian jokers, Wiki does have an entry on element 110 and it kinda fits their 
suggestion…. 

 

Wiki: Darmstadtium was first created on November 9, 1994, at the Institute for 
Heavy Ion Research (Gesellschaft für Schwerionenforschung) in Darmstadt, 
Germany, by Armbruster and Münzenberg … The team bombarded a lead-208 target 
with accelerated nuclei of nickel-62 …

 

The idea is nickel + lead fusion -> fission with the ash being different 
isotopes of the same elements, but the downfall of the attempted humor is that 
the fission would result in a plethora of elements from the double hump 
distribution – NOT the same two that fused … assuming they could fuse, which 
they can’t…

 

It’s fairly clever …

By using semiclassical method and considering Woods–Saxon and Coulomb 
potentials, the level density parameter a was calculated for three superheavy 
nuclei 270110, 278112 and 290116. Obtained results showed that the value of 
level density parameter of these nuclei is near to the simple relation a≈A/10. 
In framework of the dinuclear system model, the effects of level density 
parameter on the probability of the formation of a compound nucleus, the ratio 
of neutron emission width and fission width, and evaporation residue 
cross-section of three cold fusion reactions 62Ni+208Pb, 70Zn+208Pb and 
82Se+208Pb, leading to superheavy elements were investigated. The findings 
indicate that the level density parameter play a significant role in 
calculations of heavy-ion fusion–fission reactions. The obtained results in the 
case of a = A/12 have larger values in comparison with calculated level density 
parameter with Woods–Saxon potential (aWS) and a = A/10. The theoretical 
results of the evaporation residue cross-section are very sensitive to the 
choice of level density parameter. The calculated values with aWS are in good 
agreement with experimental values.
