Dubna suggested290114, however, viability of the 2n channel aside, I have problems with this assignment as it gives a rather long SF half-life to the termination Even-Even nuclide278Hs. N=170 is now known to be a location of low fission barrier in between the N=162 deformed shell and t...
An artificially produced radioactive element with atomic number 118, whose most stable isotope has a mass number of 294 and a half-life of 1.3 milliseconds. [oganess-(after YuriOganessian(born 1933), Russian nuclear physicist and scientific director at the Joint Institute for Nuclear Research in...

The team had successfully made element 114; the isotope they had made was not on the centre of the island, but close enough to prove it existed. ‘If there was no stability,’ Oganessian says, ’it would have a half-life of 10–19seconds. There’s no meaning to talk about an elemen...

Element 117, for example, has a half-life of about 50 thousandths of a second, meaning that within that time about half of it will decay into a lighter element. A US–Russian team first created element 117 in 20101 at the Joint Institute for Nuclear Research in Dubna, Russia. The ...
