摘要	Initial partonic eccentricities in Au + Au collisions at center-of-mass energy root s(NN) = 200 GeV are investigated by using a multiphase transport model with a string-melting scenario. The initial eccentricities in different order of harmonics are studied by using participant and cumulant definitions. Eccentricity in terms of second- ,fourth-and sixth-order cumulants as a function of number of participant nucleons are compared systematically with the traditional participant definition. The ratio of the cumulant eccentricities epsilon{4}/epsilon{2} and epsilon{6}/epsilon{4} are studied in comparison with the ratio of the corresponding flow harmonics. The conversion coefficients (upsilon(n)/epsilon(n)) are explored up to fourth-order harmonics based on the cumulant method. Furthermore, studies on transverse momentum (p(T)) and pseudorapidity (eta) dependencies of eccentricities and their fluctuations are presented. As in ideal hydrodynamics, initial eccentricities are expected to be closely related to the final flow harmonics in relativistic heavy-ion collisions, studies of the fluctuating initial condition in the AMPT model will shed light on the tomography properties of the initial source geometry.
