Spectroscopy along flerovium decay chains. II. Fine structure in odd-A ²⁸⁹Fl

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, T_1/2, 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).
