Abstract
We present measurements of the CP-violation parameters S and C for the radiative decay B0-->etaKS0gamma; for B-->etaKgamma we also measure the branching fractions and for B+-->etaK+gamma the time-integrated charge asymmetry Ach. The data, collected with the BABAR detector at the Stanford Linear Accelerator Center, represent 465×106 BB[over-bar] pairs produced in e+e- annihilation. The results are S=-0.18[subscript -0.46][superscript +0.49]±0.12, C=-0.32[superscript -0.39][superscript +0.40]±0.07, B(B0-->etaK0gamma)=(7.1[subscript -2.0][superscript +2.1]±0.4)×10[superscript -6], B(B+-->etaK+gamma)=(7.7±1.0±0.4)×10[superscript -6], and A[subscript ch]=(-9.0[subscript -9.8][superscript +10.4]±1.4)×10[superscript -2]. The first error quoted is statistical and the second systematic.
