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 ... -
Rare beta decays and the spectrum-shape method
Haaranen, Mikko (University of Jyväskylä, 2017)This is a thesis consisting of seven publications and an introductory part on theoretical studies on rare single beta decays. Firstly, the theoretical framework is applied to the computation of partial half-lives for ... -
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 ... -
Spectrum-shape method and the next-to-leading-order terms of the β-decay shape factor
Haaranen, Mikko; Kotila, Jenni-Mari; Suhonen, Jouni (American Physical Society, 2017)Effective values of the axial-vector coupling constant gA have lately attracted much attention due to the prominent role of gA in determining the half-lives of double β decays, in particular their neutrinoless mode. The ... -
