Abstract

We present the results of searches for B decays to the two charmless two-body final states B⁰ --> eta K^*0 and B⁺ --> eta K^*+, based on 20.7 fb-1 of data collected in 1999 and 2000 with the BABAR detector at PEP-II. We find the branching fractions BF(B⁰ --> eta K^*0) = (19.8^+6.5_-5.6 +/- 1.7) x 10^-6 and BF(B⁺ --> eta K^*+) = (22.1^+11.1_-9.2 +/- 3.3) x 10^-6, where the first error quoted is the statistical and the second systematic.
