Relativistic approach to the nuclear breathing mode

چکیده
Microscopic theory of the nuclear response based on relativistic meson-nucleon Lagrangian is applied to description isoscalar giant monopole resonance (ISGMR) in a variety systems. It shown that parameter-free inclusion beyond-mean-field correlations quasiparticle-vibration coupling (qPVC) type leading approximation allows for simultaneous realistic ISGMR nuclei lead, tin, zirconium, and nickel mass regions, which difficult mean-field level. The calculations employ finite-range effective interaction, which, combination with qPVC, has consistently demonstrated ability reliably describe many other structure phenomena. Systematic isotopes help reveal central role between low-energy quadrupole states placement centroids.

Nuclear Breathing Mode in the Relativistic Mean-field Theory
The breathing-mode giant monopole resonance is studied within the framework of the relativistic mean-field (RMF) theory. Using a broad range of parameter sets, an analysis of constrained incompressibility and excitation energy of isoscalar monopole states in finite nuclei is performed. It is shown that the non-linear scalar self-interaction considerably. It is observed that dynamical surface pr...
متن کاملThe Relativistic Dirac-Brueckner Approach to Nuclear Matter
An overview on the relativistic Dirac-Brueckner approach to the nuclear many-body problem is given. Different approximation schemes are discussed, with particular emphasis on the nuclear self-energy and the saturation mechanism of nuclear matter. I will further discuss extensions of the standard approach, amongst other things the inclusion of non-nucleonic degrees of freedom, many-body forces a...
متن کاملPentaquarks in a Breathing Mode Approach to Chiral Solitons∗
Although chiral soliton model predictions for the mass of the lightest exotic pentaquark, the Θ with zero isospin and unit strangeness, have been around for some time, the study of pentaquarks as baryon resonances became popular only recently when experiments indicated their existence. These experiments were stimulated by a chiral soliton model estimate suggesting that such exotic baryons might...
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
