General Comments:

2004Mo42, 2007Mo43, 2012Mo25: 270Mt produced as granddaughter of 278Nh, which was formed in 209Bi(70Zn,n) E=349 MeV reaction at RIKEN. See 278Nh Adopted Levels for details of three correlated decay chains observed.

Q-value: Estimated uncertainties (2017Wa10): ΔQ(β-)=180, ΔS(n)=490, ΔS(p)=210.

Q-value: S(2n)=14580 290, S(2p)=4670 420, Q(εp)=1940 410 (syst, 2017Wa10)

Q-value: Other Q(α)=10.30 MeV 11 from Eα=10.15 MeV 11 (from unweighted average of Eα=10.03 MeV 7 (2004Mo42) and 10.26 MeV 7 (2012Mo25)).
