Abstract
The relativistic nuclear mean-field model with derivative scalar coupl ing suggested by Zimanyi and Moszkowski is extended to asymmetric nucl ear matter by including the rho meson degree of freedom in the Lagrang ian. The extended model is then used to study the Coulomb instability of asymmetric nuclear matter at finite temperature. The critical tempe rature for the liquid-gas phase transition in nuclear matter and its d ependence on the asymmetry parameter are calculated. The limiting temp erature T(lim), which reflects Coulomb instability of hot nuclei is st udied. The calculated results are compared with those given by quantum hadrodynamics (QHD) models.
