General Comments:

1981Ho10: 164Os produced and identified in 110Cd(58Ni,xnyp), using velocity filter, and ion implantation in Si (surface-barrier and position-sensitive) detectors, followed by the observation of 160W, 156Hf α-daughter activities at the same positions.

Later studies of 164Os decay: 1996Pa01, 1996Bi07

For theoretical nuclear structure calculations, consult NSR database, for six references. These are listed in the ENSDF dataset as document records, together with about 12 theory references for α-decay half-life

Q-value: Estimated uncertainties (syst,2017Wa10): ΔQ(β-)=350, ΔS(n)=330

Q-value: S(2n)=22120 340 (syst), S(2p)=1000 150, Q(εp)=7200 160 (2017Wa10)
