摘要：
Results of study of the K+ -> pi(0)e+ nu gamma decay at OKA setup are presented. 16889 events of this decay have been observed. The branching ratio with cuts K-y* > 10 MeV, 0.6 < cos Theta*(e gamma) < 0.9 is calculated R = Br(K+ ->pi(0)e(+)ve gamma)/Br(K+ ->pi(0)e+ve)) = (0.574 +/- 0.010(stat.) +/- 0.021(syst.))x 10(-2). For the asymmetry A(xi) we get A(xi) = -0.009 +/- 0.012(stat.)
