Abstract: We present measurements of the branching fractions for B 0 -meson decays to η ′ K 0 and ω K 0 , and of the branching fractions and C P -violation charge asymmetries for B + -meson decays to η π + , η K + , η ′ π + , η ′ K + , ω π + , and ω K + . The data, collected with the BABAR detector at the Stanford Linear Accelerator Center, represent 383 × 10 6 B ¯¯¯ B pairs produced in e + e − annihilation. The measurements agree with previous results; we find no evidence for direct C P violation.
