We report a measurement of the branching fraction of the decay B-s(0) -> J/psi phi(1020), evidence and a branching fraction measurement for B-s(0) -> J/psi f(2)'(1525), and the determination of the total B-s(0) -> J/psi K+K- branching fraction, including the resonant and nonresonant contributions to the K+K- channel. We also determine the S-wave contribution within the phi(1020) mass region. The absolute branching fractions are B[B-s(0) -> J/psi phi(1020)] = (1.25 +/- 0.07(stat) +/- 0.08(syst) +/- 0.22(f(s))) x 10(-3), B[B-s(0) -> J/psi f(2)'(1525)] = (0.26 +/- 0.06(stat) +/- 0.02(syst) +/- 0.05(f(s))) x 10(-3), and B[B-s(0) -> J/psi K+K-] = (1.01 +/- 0.09(stat) +/- 0.10(syst) +/- 0.18(f(s))) x 10(-3), where the last systematic error is due to the branching fraction of b (b) over bar -> B-s(()*()) B-s(()*()). The branching fraction ratio is found to be B[B-s(0) -> J/psi f(2)'(1525)]/B[B-s(0) -> J/psi phi(1020)] = (21.5 +/- 4.9(stat) +/- 2.6(syst))%. All results are based on a 121. 4 fb(-1) data sample collected at the Upsilon(5S) resonance by the Belle experiment at the KEKB asymmetric-energy e(+)e(-) collider.
