[en] The very neutron-deficient isotopes ^114-118Ba were produced in ⁵⁸Ni induced reactions on ⁵⁸Ni, ⁶⁰Ni or ⁶³Cu targets. By on-line mass separation of BaF molecules formed in the separator ion source, exceptionally pure sources of these isotopes were available for spectroscopic studies. The β-decays of ¹¹⁴Ba (T_1/2=0.43^+0.30_-0.15 s), ¹¹⁵Ba (T_1/2=0.45±0.05 s), ¹¹⁶Ba (T_1/2=1.3±0.2 s) and ¹¹⁸Ba (T_1/2=5.2±0.2 s) were investigated for the first time. ¹¹⁴Ba, ¹¹⁵Ba and ¹¹⁶Ba were identified as β-delayed proton emitters and absolute branching ratios for this decay mode were determined to be 20±10%, >15%, and 3±1%, respectively. In the decay study of ¹¹⁸Ba several γ transitions were identified. New information was also obtained on the β-delayed γ radiation of ¹¹⁷Ba. The spectroscopic data were used to determine the production cross-sections for all these isotopes. Results of our half-life measurements and β-delayed proton studies are confronted with theoretical predictions. (orig.)
