Isospin dependence of liquid–gas phase transition in hot asymmetric nuclear matter

By using the Furnstahl, Serot and Tangʹs model, the effect of density dependence of the effective nucleon–nucleon–ρ-meson (NNρ) coupling on the liquid–gas phase transition in hot asymmetric nuclear matter is investigated. A limit pressure plim has been found. We found that the liquid–gas phase transition cannot take place if p>plim. The binodal surface for density dependent NNρ coupling situation is addressed.
