Reference: 2021WA16

References:
  A  173Hg α decay  B  170Au p decay (0.29 MS)
  C  170Au p decay (0.62 MS)  D  94Mo(78Kr,3nγ)
  E  112Sn(60Ni,3nγ) 

General Comments:

Production: 112Sn(68Ni,x) (1996Pa01).

Identification: relationship of new α group to known transitions, as obtained through a multi-dimensional analysis correlating parent energies, daughter energies, and timing of events; production reactions were 58Ni on molybdenum through tin targets and 107Ag on vanadium through nickel targets (1981Ho10).

Q-value: ΔQ(β-)=360, ΔS(n)=250, ΔS(p)=210 (syst,2021Wa16)

Q-value: S(2n)=21850 370, S(2p)=540 220, Q(εp)=10240 200 (syst,2021Wa16)
