We present results of the first experiment aimed at synthesis Mc isotopes in 243Am+48Ca reaction performed new gas-filled separator DGFRS-2 online to cyclotron DC280 Super Heavy Element Factory JINR. Fifty-five decay chains 288Mc and six assigned 289Mc were detected. The α 268Db with an energy 7.6–8.0 MeV, half-life 16+6−4h, a branch 55+20−15% was registered for time, spontaneously fissioning isotope 264Lr 4.9+2.1−1.3h identified. cross section 243Am(48Ca,3n)288Mc measured be 17.1+6.3−4.7...

For first time, a new isotope $^{275}\mathrm{Ds}$ with half-life $0.{43}_{\ensuremath{-}0.12}^{+0.29}$ ms \ensuremath{\alpha}-particle energy $11.20\ifmmode\pm\else\textpm\fi{}0.02$ MeV was synthesized in...
In this paper, we present results of the second experiment on synthesis Mc isotopes in $^{243}\mathrm{Am}+^{48}\mathrm{Ca}$ reaction performed at gas-filled separator DGFRS-2 SHE Factory JINR. The new isotope $^{286}\mathrm{Mc}$ was synthesized, and its half-life $20\begin{array}{c}+98\\ \ensuremath{-}9\end{array}$ ms \ensuremath{\alpha}-particle energy $10.71\ifmmode\pm\else\textpm\fi{}0.02$ MeV were determined.

Experiments using a $^{48}\mathrm{Ca}$ beam on $^{238}\mathrm{U}$ and $^{242}\mathrm{Pu}$ targets to produce superheavy nuclei were performed at the gas-filled separator DGFRS-2 online new cyclotron DC280 SHE Factory JINR. The decay properties of $^{286}\mathrm{Fl}$ $^{287}\mathrm{Fl}$, as well their \ensuremath{\alpha}-decay products, refined after detection 25 69 chains, respectively. In addition, 16 chains $^{283}\mathrm{Cn}$ observed in $^{238}\mathrm{U}+^{48}\mathrm{Ca}$ reaction....
The Th232+Ca48 reaction has been studied at the gas-filled separator DGFRS-2 online to cyclotron DC280 SHE Factory JINR. Three new nuclides were synthesized for first time: a spontaneously fissioning (SF) Sg268 with half-life TSF=13+17−4 s; an α decaying Hs272 Tα=0.16+0.19−0.06 s and Eα=9.63±0.02MeV; Ds276 T1/2=0.15+0.10−0.04 ms, Eα=10.75±0.03MeV, SF branch of 57%. decay properties these nuclei are in agreement systematics experimental partial half-lives α-decay energies heavy known nuclei,...
Abstract A method for obtaining 156, 155, 154m2, 154, 153 Tb radiotracers by the irradiation of a europium oxide target natural isotopic composition 27 MeV α-particles is proposed. Terbium can be efficiently separated from bulk reduction latter zinc in an acidic solution and precipitation as EuSO 4 . The optimum Zn/Eu 3+ (NH ) 2 SO /Eu molar ratios are 20 3, respectively. additionally purified gadolinium extraction chromatography using LN Resin. It demonstrated that separation attained 0.6 M...
Experiment with 48Ca beam on 238U target to produce 283Cn superheavy nucleus was performed at the new gas-filled separator DGFRS-2 on-line cyclotron DC-280 SHE Factory JINR.
