General Comments:

The following activities from 114Cs have been observed by 1978Da07, 1978Ro19, 1979Sc22, 1980Ro04, 1985Ti02

Q(ε) - S(p)=8.73 MeV 15, mass-excess: -55.10 MeV 16 (1985Ti02). To be compared with -54.531 MeV 300 (2011AuZZ)

Gammas: The γ rays are known only from 58Ni(58Ni,pnγ) reaction study

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

Q-value: ΔQ(β-)=130, ΔS(n)=70, ΔS(p)=70 (2011AuZZ)

E(level): From Eγ’s

E(γ): Uncertainties are stated as 0.1 to 0.4 keV by 2006Sm02, the evaluator assigns 0.1 to strong γ rays and 0.4 keV to weak γ rays
