Energy levels of outermost orbitals of hassium and osmium atoms in electronvolts, with and without taking relativistic effects into account. Note the lack of spin–orbit splitting (and thus the lack of distinction between d3/2 and d5/2 orbitals) in nonrelativistic calculations.

…go and if lead targets were a physics' Klondike, Oganessian responded, "Klondike may be an exaggeration [...] But soon, we will try to get elements 107 ... 108 in these reactions." Synthesis of element 108 was first attempted in 1978 by a team led by Oganessian at JINR. The team used a reaction that…
Element 107 was originally proposed to be named after Niels Bohr, a Danish nuclear/theoretical physicist, with the name nielsbohrium (Ns). This name was later changed by IUPAC to bohrium (Bh).
