英文摘要	We have investigated the exclusive, radiative B meson decays to K-2()(1430) in 89x10(6) B (B) over bar events with the BABAR detector at the PEP-II storage ring. We measure the branching fractions B(B-0-->K-2()(1430)(0)gamma)=(1.22+/-0.25+/-0.10)x10(-5) and B(B+-->K-2()(1430)(+)gamma)=(1.45+/-0.40+/-0.15)x10(-5), where the first error is statistical and the second systematic. In addition, we measure the CP-violating asymmetry A(CP)[B-0-->K-2()(1430)(0)gamma]=-0.08+/-0.15+/-0.01.
