General Comments:

1983Sc24: 175Hg identified in (92Mo,X) E=4.5-5.4 MeV/nucleon using enriched targets of Rb through Mo at GSI facility. Measured α, T1/2

1996Pa01: 175Hg from heavy-ion fusion-evaporation reactions; recoil mass separator at ANL facility. Measured Eα, T1/2.

1997Uu01: 175Hg from 144Sm(36Ar,X) E=180-230 MeV, gas-filled recoil separator (RITU) at Jyvaskyla facility. Measured α, T1/2.

2002Ro17: 175Hg from 179Tl α decay followed by 175Au ε decay; 179Tl produced by 102Pd(78Kr,X) E=340 MeV, gas-filled separator at LBNL, Measured γ, α, x rays, T1/2

2004Ke06: source from proton decay of 176Tl, measured Eα, T1/2

2009Od01: 86Sr17+ beam at 403 MeV provided by the K130 cyclotron at Jyvaskyla. Enriched (98%) 92Mo target. The recoiling residues were transported to the focal plane of the RITU He-filled magnetic separator. Measured prompt γ, α, T1/2

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

Q-value: ΔS(p)=140 (2009AuZZ,2003Au03)

Q-value: Q(εp)=10040 100, s(2n)=21560 230 (syst), s(2p)=630 120 (2009AuZZ,2003Au03)
