[en] The first order liquid-gas phase transition in nuclear matter near nuclear density is of huge importance not only in context to astrophysical relevance but also in the heavy-ion collision experiments. It forms a prominent feature in the crust of neutron star where density and temperature are relatively low as compared to the core. The liquid-gas phase transition in the nuclear matter is analogous to liquid-gas phase transition in water. The isotherms are typical Van der Waals type. Here an attempt is made to study the stability condition of these isotherms at low density for symmetric nuclear matter (SNM) using effective field theory motivated relativistic mean field (E-RMF) formulation
