报告题目: Coexistence of nuclear shapes: self-consistent mean-field and beyond
报告人: Professor Dario Vretenar (Physics Department, University of Zagreb)
A number of theoretical approaches based on the introduction of a nuclear mean-field have been systematically applied to the structure and stability of superheavy nuclei. The models that are considered are the macroscopic–microscopic approach and self-consistent mean-field methods, based either on non-relativistic or on relativistic energy density functionals. A few examples illustrate results of beyond mean-field methods that explicitly consider collective correlations related to the symmetry restoration and fluctuations in the collective coordinates. We discuss in detail the evolution of the ground state shape and of α-decay with N and Z as predicted by the different models and compare them with experimental data. Static and dynamic aspects of spontaneous and induced fission are analyzed.
