We report a measurement of the bottom-strange meson mixing phase beta(s) using the time evolution of B-s(0) -> J/psi(-> mu(+)mu(-))phi(-> K+K-) decays in which the quark-flavor content of the bottom-strange meson is identified at production. This measurement uses the full data set of proton-antiproton collisions at root s = 1.96 TeV collected by the Collider Detector experiment at the Fermilab Tevatron, corresponding to 9.6 fb(-1) of integrated luminosity. We report confidence regions in the two-dimensional space of beta(s) and the B-s(0) decay-width difference Delta Gamma(s) and measure beta(s) is an element of [-pi/2, -1.51]boolean OR[-0.06, 0.30]boolean OR[1.26, pi/2] at the 68% confidence level, in agreement with the standard model expectation. Assuming the standard model value of beta(s), we also determine Delta Gamma(s) = 0.068 +/- 0.026(stat) +/- 0.009(syst) ps(-1) and the mean B-s(0) lifetime tau(s) = 1.528 +/- 0.019(stat) +/- 0.009(syst) ps, which are consistent and competitive with determinations by other experiments.
