We present a relativistic therory of high-density matter which takes into account the short-range interaction due to the exchange of spin-2 mesons. An equation of state is derived and used to compute neutron star properties. The prediction of our theory for the values of maximum mass and moment of inertia for a stable neutron star are 1.75 M/sub sun/ and 1.68 x 10/sup 4/5 g cm/sup 2/, in very good agreement with the presently known observational bounds. The corresponding radius is found to be 10.7 km.We find that the inclusion of the spin-2 interaction reduces the disagreement between the relativistic and nonrelativistic theories in their predictions of masses and moments of inertia.
