English AbstractWe report a measurement of time-dependent cp violation parameters in b-0 -> k-s(0)eta gamma decays. the study is based on a data sample, containing 772 x 10(6)b(b)over-bar pairs, that was collected at the upsilon(4s) resonance with the belle detector at the kekb asymmetric-energy e(+)e(-) collider. we obtain the cp violation parameters of s = -1.32 +/- 0.77(stat) +/- 0.36(syst) and a = -0.48 +/- 0.41(stat) f 0.07(syst) for the invariant mass of the k-s(0)eta system up to 2.1 gev/c(2).
