英文摘要	The branching fractions of the decays B-0-->K(0)gamma and B+-->K(+)gamma are measured using a sample of 88x10(6)B(B) over bar events collected with the BABAR detector at the PEP-II asymmetric-energy e(+)e(-) collider. We find B(B-0-->K(0)gamma)=[3.92+/-0.20(stat)+/-0.24(syst)]x10(-5), B(B+-->K(+)gamma)=[3.87+/-0.28(stat)+/-0.26(syst)]x10(-5). Our measurements also constrain the direct CP asymmetry to be -0.074K(*)gamma)<0.049 and the isospin asymmetry to be -0.046
