General Comments:

1997Ja12 (also 1995Gu01): 118Ba nuclide produced and identified in 63Cu(58Ni,p2n) reaction at 4.3-4.9 MeV/nucleon. On-line mass separation at GSI facility. Measured β+-delayed x rays and γ rays

2012WiZY, 2011Ad10: 40Ca(78Kr,X)118Ba*,E=5.5 MeV/nucleon. Measured fragments with Z=3-28 in singles and in coincidence with light charged particles emitted by binary decays of 118Ba compound nucleus using the 4π-INDRA array at GANIL. Deduced center-of-mass kinetic energy distribution of fragments, total kinetic energies (TKEs), and inclusive cross-section distributions of fragments with charge Z=3-28. Comparison with predictions of statistical model.

Theoretical calculations: 56 primary references (34 for structure and 22 for decay modes and half-lives) in the NSR database available at www.nndc.bnl.gov/nsr/.

Q-value: Estimated uncertainties (2021Wa16): 360 for Q(β-), 320 for S(n), 210 for S(p), 200 for Q(α)

Q-value: Q(ε)=6210 200, Q(εp)=4700 200, S(2n)=23960 280, 3730 200 (syst, 2021Wa16)

Jπ(level): As proposed by 1998Sm01, based on band assignments and systematics of even-even nuclei. Strong arguments are lacking since no details of angular distributions/correlations measurements are available.
