Abstract
The equation of state for anisotropic, cold nuclear matter is studied in the framework of Walecka's mean field theory. The energy density and the pressures are calculated for two simple cases which may be relevant in the description of heavy-ion collisions: (i) the Fermi surface consists of two, non-overlapping, Lorentz elongated spheres, (ii) the Fermi surface is a reflection- and axial-symmetric ellipsoid. No second minimum of the energy density is produced by the anisotropy. This fact is connected with the repulsive character of the vector mesons.
