E(level): If ΔEγ not given, |+0.30 keV assumed for least-squares fitting
E(level): From least-squares fit to Eγ’s, assuming Δ(Eγ)=0.3 keV for each γ ray
Jπ(level): As proposed by 2005Ur01 and 2006Lu12 based on band assignments, systematics and model predictions, except that parentheses have been added here due to lack of strong supporting arguments.

First identification of 111Tc nuclide by 1988Pe13 from fission of 238U induced by protons. Later works from the same and associated groups: 1992PeZX thesis, 1996Me09 and 1998Pf01, where delayed-neutron branch and details of γ rays to 111Ru were studied.
Except for isotopic identification of 111Mo, no information is available about its half-life or its β decay to 111Tc levels.
