Centroids of Gamow-Teller transitions at finite temperature in fp-shell neutron-rich nuclei
نویسنده
چکیده
The temperature dependence of the energy centroids and strength distributions for Gamow-Teller (GT) 1+ excitations in several fp-shell nuclei is studied. The quasiparticle random phase approximations (QRPA) is extended to describe GT states at finite temperature. A shift to lower energies of the GT+ strength is found, as compared to values obtained at zero temperature.

We show that the presently available data on the Gamow-Teller (GT) strength in mid-f p-shell nuclei are proportional to the product of the numbers of valence protons and neutron holes in the full f p-shell. This observation leads to important insights into the mechanism for GT quenching and to a simple parametrization of the Gamow-Teller strengths important for electron capture by f p-shell nuc...
متن کاملGamow-Teller strength distributions for nuclei in presupernova stellar cores.
Electron-capture and β-decay of nuclei in the core of massive stars play an important role in the stages leading to a type II supernova explosion. Nuclei in the f-p shell are particularly important for these reactions in the post Siliconburning stage of a presupernova star. In this paper, we characterise the energy distribution of the Gamow-Teller Giant Resonance (GTGR) for midfp-shell nuclei i...

A systematic study of the total β-decay half-lives and β-delayed neutron emission probabilities is performed. The β-strength function is treated within the self-consistent density-functional + continuum-QRPA framework including the Gamow-Teller and first-forbidden transitions. The experimental total β-decay half-lives for the Ni isotopes with A ≤76 are described satisfactorily. The half-lives p...
متن کاملGamow-Teller strengths and electron-capture rates for p f -shell nuclei of relevance for late stellar evolution
Background: Electron-capture reaction rates on medium-heavy nuclei are an important ingredient for modeling the late evolution of stars that become core-collapse or thermonuclear supernovae. The estimation of these rates requires the knowledge of Gamow-Teller strength distributions in the β+ direction. Astrophysical models rely on electron-capture rate tables largely based on theoretical models...
متن کاملShape evolution and Gamow-Teller β-decay of neutron-rich A∼100 nuclei within beyond-mean-field approach
Our recent investigations represent an attempt to the self-consistent description of exotic phenomena in neutron–rich A∼100 nuclei [1, 2] within the complex Excited Vampir variational model with symmetry projection before variation using a realistic effective interaction in a large model space. The triple shape coexistence and the shape evolution in the N=58 Sr and Zr isotopes, the shape evolut...
