dc.description.abstract	We adapt the proton-neutron finite-amplitude method, which in its original form is an efficient implementation of the Skyrme quasiparticle random phase approximation, to include the coupling of quasiparticles to like-particle phonons. The approach allows us to add beyond-quasiparticle random-phase approximation correlations to computations of Gamow-Teller strength and β-decay rates in deformed nuclei for the first time. We test the approach in several deformed isotopes for which measured strength distributions are available. The additional correlations dramatically improve agreement with the data, and will lead to improved global β-decay rates.	en

Effective axial-vector strength within proton-neutron deformed quasiparticle random-phase approximation

Delion, D. S.; Dumitrescu, A.; Suhonen, J. (American Physical Society, 2019)

We use the available experimental Gamow-Teller β− and β+/EC (electron-capture) decay rates between 0+ and 1+ ground states in neighboring even-even and odd-odd nuclei, combined with 2νββ half-lives, to analyze the influence ...
Statistical analysis of β decays and the effective value of gA in the proton-neutron quasiparticle random-phase approximation framework

Deppisch, Frank F.; Suhonen, Jouni (American Physical Society, 2016)

We perform a Markov chain Monte Carlo (MCMC) statistical analysis of a number of measured groundstate-to-ground-state single β+/electron-capture and β− decays in the nuclear mass range of A = 62–142. The corresponding ...

K.; Vencelj, M.; Yavor, M. I.; Zhao, J. (American Physical Society (APS), 2021)

Mass measurements of the nuclides 69As, 70,71Se, and 71Br, produced via fragmentation of a 124Xe primary beam at the Fragment Separator (FRS) at GSI, have been performed with the multiple-reflection time-of-flight mass ...
