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.

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.
