Experiments on the synthesis of superheavy nuclei ²⁸⁴Fl and ²⁸⁵Fl in the ^{239, 240}Pu + ⁴⁸Ca reactions

NUCLEAR REACTIONS ²⁴⁰Pu(⁴⁸Ca, 3n)²⁸⁵Fl, E=245, 250 MeV; ²⁴⁰Pu(⁴⁸Ca, 4n)²⁸⁴Fl, E=245, 250 MeV; ²³⁹Pu(⁴⁸Ca, 3n)²⁸⁴Fl, E=245 MeV; measured evaporation residues (ER), α, and SF fragments, ER-α and ER-SF correlated events, σ using DGFRS separator at U400 cyclotron facility of FLNR-JINR. Decay studies. Super heavy nuclei. Systematics of cross sections.

RADIOACTIVITY ²⁸⁴Fl(SF), ²⁸⁵Fl(α)[from ^239,240Pu(⁴⁸Ca, xn), E=245, 250 MeV]; ²⁸¹Cn, ²⁷⁷Ds, ²⁷³Hs, ²⁶⁹Sg(α), ²⁶⁵Rf[from ²⁸⁵Fl α decay chain]; measured E_ER, Eα, E_SF, T_1/2; deduced Q(α). Systematics of SF half-lives and α-decay energies.
