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