The calculation of ground state energy of nuclear matter with neutron excess, which has been done up to the second order in ( k f r c ) (where k f is the Fermi momentum and r c is the hard core radius), is extended here to include the third order term. By applying Brueckner theory in the low density limit we calculate this term and then we expand the energy in terms of α (α = ( N ‐ Z )/ A ) up to the fourth order to get the volume and symmetry terms of the Weizsäcker semiemperical mass formula. We also calculate the volume and symmetry parts of the compressibility up to ( k f r c ) 3 .
