Publikováno v: Journal of Physics: Conference Series. 2453:012017

The charge-exchange subtracted second random-phase approximation, based on Skyrme functionals, is employed to investigate the Gamow-Teller resonances in several nuclei, located in different regions of the nuclear chart. The amount of Gamow-Teller str

Quenching of Gamow-Teller strengths and two particle -- two hole configurations

Autor: Danilo Gambacurta, Marcella Grasso

We apply the charge-exchange subtracted second random-phase approximation (SSRPA), based on Skyrme functionals, to investigate Gamow-Teller resonances in several closed-shell and closed-subshell nuclei, located in different regions of the nuclear cha
