Anatomy of nuclear shape transition in the relativistic mean field theory
نویسندگان
چکیده
A detailed microscopic study of the temperature dependence of the shapes of some rare-earth nuclei is made in the relativistic mean field theory. Analyses of the thermal evolution of the single-particle orbitals and their occupancies leading to the collapse of the deformation are presented. The role of the nonlinear σ−field on the shape transition in different nuclei is also investigated; in its absence the shape transition is found to be sharper.

Nuclear shape transition at finite temperature in a relativistic mean field approach
The relativistic Hartree-BCS theory is applied to study the temperature dependence of nuclear shape and pairing gap for 166Er and 170Er. For both the nuclei, we find that as temperature increases the pairing gap vanishes leading to phase transition from superfluid to normal phase as is observed in nonrelativistic calculation. The deformation evolves from prolate shapes to spherical shapes at T ...
متن کاملPhase transition of the nucleon-antinucleon plasma in a relativistic mean-field theory
Studying Walecka's mean-field theory we find that one can reproduce the observed binding ener' gy and density of nuclear matter within experimental precision in an area characterized by a line in the coupling-constant plane. A Part of this line defines systems which exhibit a phase transition around T,-200 MeV for Zero baryon density. The rest corresponds to such systems where the phase transit...
متن کاملVector meson radiation in relativistic heavy-ion collisions
The (σ, ω) model in mean-field approximation where the meson fields are treated classically, describes much of observed nuclear structure and has been employed to describe the nuclear equation of state up to the quark-gluon phase transition. The acceleration of the meson sources, for example, in relativistic heavy-ion collisions, should result in bremsstrahlung-like radiation of the meson field...
متن کاملRelativistic mean-field description of the dynamics of giant resonances
The relativistic mean-field theory provides a framework in which the nuclear many-body problem is described as a self-consistent system of nucleons and mesons. In the mean-field approximation, the self-consistent time evolution of the nuclear system describes the dynamics of collective motion: nuclear compressibility from monopole resonances, regular and chaotic dynamics of isoscalar and isovec...
متن کاملShape transition in some rare-earth nuclei in relativistic mean field theory
A systematic study of the temperature dependence of the shapes and pairing gaps of some isotopes in the rare-earth region is made in the relativistic Hartree-BCS theory. Thermal response to these nuclei is always found to lead to a phase transition from the superfluid to the normal phase at a temperature T∆ ∼ 0.4 − 0.8 MeV and a shape transition from prolate to spherical shapes at Tc ∼ 1.0−2.5 ...
