S(n)= 9950 keV SYS(p)= 1170 keV SYQ(α)= 6680 keV 50
Reference: 2012WA38

References:
  A  164Ir p decay (70 μs)  B  167Pt α decay (0.78 MS)
  C  106Cd(60Ni,3nγ) 

General Comments:

163Os produced and identified by 1981Ho10, 1996Bi07 and 1996Pa01 in various heavy-ion fusion reactions followed by fragment-mass analysis (1996Bi07), recoil-mass separation (1996Pa01) and α-decay measurements

Q-value: Estimated uncertainties (2012Wa38): 590 for S(n), 360 for S(p)

Q-value: S(2n)=22310 500, S(p)=410 360, Q(εp)=10330 300 (syst,2012Wa38)
