dc.descriptionIn a sample of 19 million produced B mesons we have observed decays B -> eta K*, and improved our previous measurements of B -> eta' K. The branching fractions we measure for these decay modes are B(B+ -> eta K*+) = (27.3 +9.6 -8.2 (stat) +- 5.0 (sys)) * 10^(-6), B(B0 -> eta K*0) = (13.8 +5.5 -4.4 +- 1.7) * 10^(-6), B(B+ -> eta' K+) = (80 +10 -9 +- 8) * 10^(-6), and B(B0 -> eta' K0) = (88 +18 -16 +- 9) * 10^(-6). We have searched with comparable sensitivity for related nonstrange decays, and report upper limits for these rates. All quoted results are preliminary.
