Livermorium

Livermorium: the essentials

Brief description: an isotope of livermorium, Element 116 (²⁹²Lv) was identified in the reaction of ²⁴⁸Cm with ⁴⁸Ca. It is very shortlived and decomposes to a known isotope of element 114, ²⁸⁸₁₁₄Fl.

Isolation

Isolation: results published on the 6th December 2000 concerning recent experiments at Dubna in Russia (involving workers from The Joint Institute for Nuclear Research, Dubna, Russian Federation; The Lawrence Livermore National Laboratory, California, USA; The Research Institute of Atomic Reactors, Dimitrovgrad, Russian Federation; and The State Enterprise Electrohimpribor, Lesnoy, Russian Federation) describe the decay of the isotope ²⁹²Lv (produced in the reaction of ²⁴⁸Cm with ⁴⁸Ca) to ²⁹²Fl.

²⁴⁸₉₆Cm + ⁴⁸₂₀Ca → ²⁹²₁₁₆Lv + 4 n

This decayed 47 milliseconds later as follows to a previously identified isotope of element 114, Fl.

²⁹²₁₁₆Lv → ²⁸⁸₁₁₄Fl + ⁴₂He
