General Comments:

Calculations, compilations:

g.s. properties: 1997Mo25, 1995Mo29

Pion emission: 1991Io03

Single-particle Nilsson levels: 1994Cw02

1994Cw02 calculate the following single-particle level sequence: g.s. 1/2[620], 0.01 MeV 11/2[725], 0.02 MeV 3/2[622], 0.08 MeV 7/2[613], 0.27 MeV 9/2[615]

209Bi(55Mn,n) 5.5 MeV/nucleon, fission tracks observed with T1/2≈1.1 s ascribed to 255Rf, the granddaughter of 263Hs. T1/2 of 263Hs was not measured. The observation of 255Rf indicates substantial α decay branch of 263Hs (1984DeZO,1984Og03,1984Og02).

Q-value: Note: Current evaluation has used the following Q record

Q-value: Estimated ΔS(p)=500, estimated ΔQ(α)=300 (1995Au04)
