General Comments:

1998Da03, 1999Ry04, 2001Se03, 2002Cu01, 2002Kr04, 2003BaZZ, 2005Bi24, 2007KaZO, 2008Ka16, all of them using the 92Mo(54Fe,p4n) reaction

Ground-state deformation: from the analysis of the proton radioactivity data, β≈0.3 was deduced (1998Da03, 1999Ry04, 1999Ma05, 2000Bb02, 2000Kr07, 2001Es01). α similar value was deduced following the study of the high-spin data (2001Se03). More recent calculations deduced generally larger values of deformation, β=0.3-0.4 (2005Fe06, 2007Ka60, 2008Ka16)

Q-value: ΔS(n)=640, ΔQ(α)=570 (syst,2021Wa16)

Q-value: S(2p)=810 500, Q(εp)=8830 900 (syst,2021Wa16)

E(level): From least-square fit to Eγ for γ decaying states

Jπ(level): For γ decaying states, the assignments are based on the γ energy and intensity pattern expected for band members, supported by cranked-shell model calculations and comparisons with neighboring nuclei
