General Comments:

Identification: cross bombardments and comparison of excitation functions for 168Yb-174Yb(16O,xn), 169Tm(19F,xn), and 162Er-166Er(20Ne,xn), producing known and new Pt activities (1966Si08).

See 1984Al36 for analysis of mass and proton-stability data for 173Pt.

Other reaction: Mo(84Sr,xnyp). See 2001Sm04, 2003Sm01 for study of energy-spin entry distributions.

E(level): From Eγ.

Jπ(level): From Sn(58Ni,xnγ), except as noted. Assigned by 2006Jo04, 2005Jo18 as a probable (ν i13/2) band, analogous to structure of 175Pt.

E(γ): From Sn(58Ni,xnγ); uncertainties unstated by authors.
