摘要：

We report a measurement of the ratios of the decay rates of the B+, B-0, and B-s(0) mesons into exclusive final states containing a J/psi, meson. The final states were selected from 19.6 pb(-1) of <p(p)over bar> collisions recorded by the Collider Detector at Fermilab. These data are interpreted to determine the b quark fragmentation fractions f(u), f(d), and f(s). We also determine the blanching fractions for the decay modes B-+ --> J/psi K+, B+ --> J/psi K*(892)(+), B-0 --> J/psi K-0, B-0 --> J/psi K*(892)(0), and B-s(0) --> J/psi phi(1020). We discuss the implications of these measurements to B meson decay models.
