We measured the first azimuthal distributions of triple-differential cross sections of neutrons emitted in heavy-ion collisions, and compared their maximum azimuthal anisotropy ratios with Boltzmann-Uehling-Uhlenbeck (BUU) calculations with a momentum-dependent interaction. By restricting the analysis to free neutrons, the BUU calculations of the triple-differential cross sections for positive rapidity neutrons emitted at polar angles from 7[degree] to 27[degree] agree generally with the data; however, the polar-angle dependence of the maximum azimuthal anisotropy ratio for these free neutrons is insensitive to the size of the nuclear incompressibility modulus [ital K] characterizing the nuclear matter equation of state.
