
Modernization of existing accelerators (U400М & U400)
Creation of the new experimental hall (≈ 2600 м2)
Development and creation of next generation set-ups
Creation of high current heavy ion accelerator
(A≤ 100, E ≤ 10 MeV ·A , I≥10 pµA)
The DRIBs-III project should be realized
at simultaneous implementation of SHE
research program
Provisional Recommendation - Names and Symbols of
the Elements with Atomic Numbers 114 and 116
08 December 2011
A joint IUPAC/IUPAP Working Party (JWP) has confirmed the
discovery of the elements with atomic numbers 114 and 116.
In accord with IUPAC procedures, the discoverers proposed
names as follows:
 Flerovium and symbol, Fl, for the element with Z = 114 and
 Livermorium with the symbol Lv for the element with Z = 116.
The Inorganic Chemistry Division recommended these proposals
for acceptance.
