Systematics of Gamow-Teller beta decay “Southeast” of 100Sn

Abstract.

The energy centroids and integrated strengths of Gamow-Teller transitions in the \( \beta^{+}_{}\) and electron-capture decay are analyzed for nuclei whose proton number Z and neutron number N are restricted to 44 \( \leq\) Z \( \leq\) 50 and 50 \( \leq\) N \( \leq\) 58 . The analysis is based on data measured both with high-resolution \( \gamma\) -ray spectrometry and total \( \gamma\) -ray absorption techniques. The dependence of the considered quantities on the relative neutron excess are established after taking into account the effects due to the Coulomb interaction and mean-field level occupancies. An extrapolation of this dependence to the lightest known tin isotopes is used to estimate the decay characteristics of 100Sn and 101Sn . The values extrapolated for the half-lives of 100Sn and 101Sn agree with experimental data. Using the extrapolated values together with shell model predictions, the Q values for the electron-capture decay of 100Sn is evaluated. The quenching factor for \( \beta^{+}_{}\) and the electron-capture decay of the nuclei under consideration here is established to be 0.56(2) with a possible weak dependence on N - Z .
