Q(β-)=7761 keV 14S(n)= 6061 keV 14S(p)= 1.176×104 keV 3Q(α)= -7727 keV 14
Reference: 2012WA38

General Comments:

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.

Mass measurement: 2006MaZZ

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

Q-value: Estimated uncertainty from 2003Au03: ΔSP=ΔQA=420

Q-value: Q(β-n)=2690 120 (2003Au03)

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.
