In this paper, we report a measurement of the branching fraction of the decay $B_{s}^{0} \to J / ψ Φ (1020)$ , evidence and a branching fraction measurement for $B_{s}^{0} \to J / ψ f_{2}^{'} (1525)$ , and the determination of the total $B_{s}^{0} \to J / ψ K^{+} K^{-}$ branching fraction, including the resonant and non-resonant contributions to the K+K– channel. We also determine the S-wave contribution within the Φ(1020) mass region. The absolute branching fractions are B[ $B_{s}^{0} \to J / ψ Φ (1020)$ ] = (1.25 ± 0.07(stat) ± 0.08(syst) ± 0.22(fs)) × 10^–3, B[ $B_{s}^{0} \to J / ψ f_{2}^{'} (1525)$ ] = (0.26 ± 0.06(stat) ± 0.02(syst) ± 0.05(fs)) × 10^–3 and B[ $B_{s}^{0} \to J / ψ K^{+} K^{-}$ ] = (1.01 ± 0.09(stat) ± 0.10(syst) ± 0.18(fs)) × 10^–3, where the last systematic error is due to the branching fraction of bb¯→ B$$^{(*)}_{s}$$B$$^{(*)}_{s}$$. The branching fraction ratio is found to be B[ $B_{s}^{0} \to J / ψ f_{2}^{'} (1525)$ ]/B[ $B_{s}^{0} \to J / ψ Φ (1020)$ ] = (21.5 ± 4.9(stat) ± 2.6(syst)). All results are based on a 121.4 fb^–1 data sample collected at the Υ(5S) resonance by the Belle experiment at the KEKB asymmetric-energy e⁺e^– collider.
