“…Finite temperature ThomasFermi framework with the subtraction technique [12] has been employed for this purpose. Two effective interactions, namely the modified Seyler-Blanchard (SBM) [13,14] and the SkM * [15] interactions that give practically the same symmetry coefficient (∼ 31 MeV) at their respective saturation densities have been used in our calculations. Dynamical changes in the energy mass m ω with temperature is also taken into account following the prescription of Refs.…”

The temperature dependence of the symmetry energy and the symmetry free energy coefficients of atomic nuclei is investigated in a finite temperature Thomas-Fermi framework employing the subtraction procedure. A substantial decrement in the symmetry energy coefficient is obtained for finite systems, contrary to those seen for infinite nuclear matter at normal and somewhat subnormal densities. The effect of the coupling of the surface phonons to the nucleonic motion is also considered; this is found to decrease the symmetry energies somewhat at low temperatures.

“…It would be interesting to know whether this is a precursor to the liquid-gas phase transition in the finite nuclei. Theoretical analysis of infinite nuclear matter (symmetric as well as asymmetric), both in the nonrelativistic [4,5] and relativistic framework [6,7] predict Van der Waals type isotherms in their equation of state (EOS) implying coexistence of liquid and gas phases. Finite size effects and the Coulomb interaction between protons might change such a behavior, but the EOS of realistic nuclei, calculated only recently [8] in the non-relativistic Thomas-Fermi (TF) theory display same kind of isotherms, liquid-gas coexistence and a liquid-gas phase transition at a temperature quite below the critical temperature for infinite nuclear matter.…”

“…Specifica1ly, at zero temperature our model is very similar to the Thomas-Fermi model recently developed by Myers and Swiatecki [2] and, therefore, we preserve the very good reproduction they obtain for such important properties as binding energies, matter distributions, and the energy-dependent optical potential. Independently, a rather similar model was recently employed by Bandyopadhyay et al [3] for a range of thermostatic properties of finite and infinite nuclear systems.…”
