General Comments:

Identification: 1981Ho10 unambiguously assign a new α group to 168Pt by relating it to known transitions through a multi-dimensional analysis correlating parent energies, daughter energies, and the timing of events. The production reactions involved 58Ni beam on tin targets.

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

Q-value: ΔS(n)=460 (2003Au03, 2009AuZZ).

E(level): Based on adopted Eγ. Excited states are shown as uncertain because order of γ cascade in (58Ni,2nγ) could not Be established due to similarity between intensities of the transitions.

Jπ(level): From probable band structure, except as noted.

E(γ): From 192Mo(78Kr,2nγ).
