The quenching of the weak axial-vector coupling strength, gA, in nuclear β decays is reviewed. The quenching is discussed for both the Gamow–Teller decays and the forbidden β decays of different variants. Both the historical background and the present status are reviewed and compared with each other. Possible new measurements are urged, whenever relevant for determining the amount of gA quenching.

Confirmation of gA quenching using the revised spectrum-shape method for the analysis of the 113Cd β-decay as measured with the COBRA demonstrator Kostensalo, Joel; Suhonen, Jouni; Volkmer, Juliane; Zatschler, Stefan; Zuber, Kai (Elsevier, 2021)In this article we present an updated spectrum-shape analysis of the113Cd fourfold forbidden non-uniqueβ-decay transition in order to address the quenching of the weak axial-vector coupling gA in low-momentum exchange ...
Suhonen, Jouni (Frontiers Research Foundation, 2017)In this review the quenching of the weak axial-vector coupling strength, gA, is discussed in nuclear β and double-β decays. On one hand, the nuclear-medium and nuclear many-body effects are separated, and on the other ...
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 ...
Electron spectra in forbidden β decays and the quenching of the weak axial-vector coupling constant gA Kostensalo, Joel; Haaranen, Mikko; Suhonen, Jouni (American Physical Society, 2017)Evolution of the electron spectra with the effective value of the weak axial-vector coupling constant gA was followed for 26 first-, second-, third-, fourth- and fifth-forbidden β− decays of odd-A nuclei by calculating the ...
