- W3132054264 abstract "The $ensuremath{beta}$ decay of $^{101,102}mathrm{Zr}$ and $^{109}mathrm{Tc}$ was studied using the technique of total absorption spectroscopy. The experiment was performed at the National Superconducting Cyclotron Laboratory using the Summing NaI(Tl) (SuN) detector in the first-ever application of total absorption spectroscopy with a fast beam produced via projectile fragmentation. The $ensuremath{beta}$-decay feeding intensity and Gamow-Teller transition strength distributions were extracted for these three decays. The extracted distributions were compared to three different quasiparticle random-phase approximation (QRPA) models based on different mean-field potentials. A comparison with calculations from one of the QRPA models was performed to learn about the ground-state shape of the parent nucleus. For $^{101}mathrm{Zr}$ and $^{102}mathrm{Zr}$, calculations assuming a pure shape configuration (oblate or prolate) were not able to reproduce the extracted distributions. These results may indicate that some type of mixture between oblate and prolate shapes is necessary to reproduce the extracted distributions. For $^{109}mathrm{Tc}$, a comparison of the extracted distributions with QRPA calculations suggests a dominant oblate configuration. The other two QRPA models are commonly used to provide $ensuremath{beta}$-decay properties in $r$-process network calculations. This work shows the importance of making comparisons between the experimental and theoretical $ensuremath{beta}$-decay distributions, rather than just half-lives and $ensuremath{beta}$-delayed neutron emission probabilities, as close to the $r$-process path as possible." @default.
