The photon spectrum in B -> X_s gamma decay, where X_s is any strangehadronic state, is studied using a data sample of 88.5 million e+e- ->Upsilon(4S) -> BBbar decays collected by the BaBar experiment at SLAC. Thepartial branching fraction, Delta B(B -> X_s gamma)=(3.67 +- 0.29(stat.) +-0.34(sys.) +- 0.29(model)) times 10^-4, the first moment <E_gamma>=2.288 +-0.025 +- 0.017 +- 0.015 GeV and the second moment <E_gamma^2> - <E_gamma>^2=0.0328 +- 0.0040 +- 0.0023 +- 0.0036 GeV^2 are measured for the photon energyrange 1.9 GeV < E_gamma < 2.7 GeV. They are also measured for narrower E_gammaranges. The moments are then fit to recent theoretical calculations to extractthe Heavy Quark Expansion parameters, m_b and mu_pi^2, and to extrapolate thepartial branching fraction to E_gamma>1.6 GeV. In addition, the direct CPasymmetry A_CP(B -> X_(s+d) gamma) is measured to be -0.110 +- 0.115(stat.) +-0.017(sys.).Comment: 8 pages 1 figure, submitted to PR
