RADIOACTIVITY 289Fl(α) [from 244Pu(48Ca, X), E=6.02 MeV/nucleon]; 285Cn(α) [from 289Fl(α)]; 281Ds(α) [from 285Cn(α)]; 277Hs(SF) [from 281Ds(α)]; measured decay products, Eα, Iα, Eβ, Iβ αβ-coin, αα-coin, (fragment)αα-coin; deduced Q-values, T1/2, branching ratios, hindrance factor. 289Fl, 285Cn, 281Ds; deduced J, π and δ assignments based on the derived decay path. Comparison with structure calculations based on the symmetry-conserving configuration mixing theory. Gas-filled recoil separator TASCA was used to transmit, select, and focus the flerovium ions into an upgraded version of the TASISpec decay station consisting of implantation DSSD, veto DSSD and set of HPGe detectors (GSI).
