Superheavy nuclei with the vector self-coupling of the ω-meson in the relativistic mean-field theory
We have studied properties and shell structure of the superheavy elements from Z = 102 to Z = 120 within the framework of the RMF theory. The region of study spans nuclides with neutron numbers N = 150 − 190. The Lagrangian model NL-SV1 with the inclusion of the vector self-coupling of the ω-meson has been employed in this work. We have performed RMF + BCS calculations for an axially deformed c...
متن کاملThe Meson Theory of Nuclear Forces I. General Theory
In this paper, the meson theory of nuclear forces is presented in a simplified way, As in Yukawa's first paper, the forces between two nuclear particles are derived directly from the field equations and the Hamiltonian of the meson field ($2,3), without quantization of the field. The charge dependence of the forces is discussed (f4) and it is found that only two assumptions are in agreement wit...
متن کاملTheory of Nuclear Reactions Leading to Superheavy Elements
Dynamical reaction theory is presented for synthesis of superheavy elements. Characteristic features of formation and surviving are discussed, which combinedly determine final residue cross sections of superheavy elements. Preliminary results on Z=114 are also given.
متن کاملThermal Meson properties within Chiral Perturbation Theory
We report on our recent work about the description of a meson gas below the chiral phase transition within the framework of Chiral Perturbation Theory. As an alternative to the standard treatment, we present a calculation of the quark condensate which combines the virial expansion and the meson-meson scattering data. We have also calculated the full one-loop elastic pion scattering amplitude at...
متن کاملNuclear Matter in Relativistic Mean Field Theory with Isovector Scalar Meson
Relativistic mean field (RMF) theory of nuclear matter with the isovector scalar mean field corresponding to the δ-meson [a0(980)] is studied. While the δ-meson mean field vanishes in symmetric nuclear matter, it can influence properties of asymmetric nuclear matter in neutron stars. The RMF contribution due to δ-field to the nuclear symmetry energy is negative. To fit the empirical value, Es ≈...
