Gamow-Teller resonances and beta decay half-lives of nuclei at finite temperature

XIV. International Conference on Nuclear Structure Properties, NSP2021, Konya, Türkiye, 2 - 04 Haziran 2021, ss.57

Presently, understanding the behavior and properties of nuclei under extreme conditions of isospin

and temperature is a major area of interest within the field of nuclear physics because of its

relevance to better understand the behavior of nuclei and some astrophysical processes. In this

framework, the nuclear energy density functional theory is known as a reliable and powerful tool to

study the ground-state and excited-state properties of nuclei all over the nuclear chart. In this talk, I

will present our results for the Gamow-Teller excitations in nuclei using the finite temperature

proton-neutron QRPA based on the relativistic nuclear energy density functional theory. The effect of

the temperature on the excitation energies and strength functions of the Gamow-Teller excitations

will be investigated for the selected open and closed-shell nuclei. I will also discuss the interplay

between the temperature and pairing effects at low temperatures, where both effects are relevant.

Finally, the impact of temperature on beta decay half-lives of nuclei will be presented.
