Scaling in Relativistic Thomas–Fermi Approach for Nuclei
By using the scaling method we derive the virial theorem for the relativistic mean field model of nuclei treated in the Thomas–Fermi approach. The Thomas–Fermi solutions statisfy the stability condition against scaling. We apply the formalism to study the excitation energy of the breathing mode in finite nuclei with several relativistic parameter sets of common use. PACS: 21.60.-n; 24.30.Cz; 21...
متن کاملRelativistic Thomas-fermi Model at Finite Temperatures
We briefly review the Thomas-Fermi statistical model of atoms in the classical non-relativistic formulation and in the generalised finite-nucleus relativistic formulation. We then discuss the classical generalisation of the model to finite temperatures in the non-relativistic approximation and present a new relativistic model at finite temperatures, investigating how to recover the existing the...
متن کاملLiquid-gas phase transition in nuclei in the relativistic Thomas-Fermi theory
The equation of state (EOS) of finite nuclei is constructed in the relativistic Thomas-Fermi theory using the non-linear σ − ω − ρ model. The caloric curves are calculated by confining the nuclei in the freeze-out volume taken to be a sphere of size about 4 to 8 times the normal nuclear volume. The results obtained from the relativistic theory are not significantly different from those obtained...
متن کاملStability of Relativistic Matter via Thomas–fermi Theory
A Thomas-Fermi-Weizsäcker type theory is constructed, by means of which we are able to give a relatively simple proof of the stability of relativistic matter. Our procedure has the advantage over previous ones in that the critical value of the fine structure constant, α, is raised to 0.77 (recall that the critical value is known to be less than 2.72). When α = 1/137, the largest nuclear charge ...
متن کاملCaloric Curve for Finite Nuclei in Thomas-fermi Theory
In a finite temperature Thomas-Fermi theory with realistic nuclear interactions, we construct caloric curves for finite nuclei enclosed in a sphere of about 4− 8 times the normal nuclear volume. The specific heat capacity Cv shows a peaked structure that is possibly indicative of a liquid-gas phase transition in finite nuclear systems.
