Abstract
Event shapes for Au + Au collisions at 11.4 GeV/c per nucleon were stu died over nearly the fun solid angle with the E877 apparatus. The anal ysis was performed by Fourier expansion of azimuthal distributions of the transverse energy (E(T)) measured in different pseudorapidity inte rvals. For semicentral collisions a pronounced event anisotropy is ide ntified with a clear forward-backward anticorrelation. In the forward pseudorapidity interval up to 9% of the E(T) is in a directed componen t. The signal decreases for peripheral and very central collisions.
