英文摘要	We report observations of radiative B meson decays into the K(+)pi(-)gamma and K(+)pi(-)pi(+)gamma final states. In the B-0-->K(+)pi(-)gamma channel, we present evidence for decays via an intermediate tensor meson state with a branching fraction of B(B-0-->K-2()(1430)(0)gamma)=[1.3+/-0.5(stat)+/-0.1(syst)]x10(-5). We measure the branching fraction B(B+-->K(+)pi(-)pi(+)gamma)=[2.4+/-0.5(stat) (+0.4)(-0.2)(syst)]x10(-5), in which the B+-->K(0)pi(+)gamma and B+-->K(+)rho(0)gamma channels dominate. The analysis is based on a data set of 29.4 fb(-1) recorded by the Belle experiment at the KEKB collider.
