General Comments:

Produced and identified by 1993WoZY, 1993Li18; from 92Mo(58Ni,X), E=287 MeV reaction.

The level scheme of 146Tm was studied by two experimental groups (2005Ro40,2006Ta08) using the reactions 92Mo(58Ni,3npγ) and 58Ni(92Mo,3npγ) for producing this nucleus. Five delayed proton lines were detected; half-lives of p-decaying states were measured (see comment in (HI,xnγ) dataset). Rotational band levels were studied in 58Ni(92Mo,3npγ) reaction.

Q-value: ΔS(n)=280, ΔQ(α)=540, Q(εp)=10940 200 (syst,2012Wa38)
