Abstract

fetched live from OpenAlex

High-angular-momentum states in $^{64}\mathrm{Zn}$ were populated in the $^{40}\mathrm{Ca}(^{28}\mathrm{Si},4p)$ reaction at a beam energy of $122\phantom{\rule{0.3em}{0ex}}\text{MeV}$. Evaporated, light, charged particles were identified by the Microball, while $\ensuremath{\gamma}$ rays were detected using the Gammasphere array. The main focus of this paper is on two strongly coupled, collective bands. The yrast band, which was previously known, has been linked to lower-lying states establishing the excitation energies and angular momenta of in-band states for the first time. The newly identified excited band decays to the yrast band but firm angular-momentum assignments could not be made. In order to interpret these structures cranked-Nilsson-Strutinsky calculations have been performed. The calculations have been extended to account for the distribution of nucleons within a configuration. The yrast collective band is interpreted as based on the $\ensuremath{\pi}{({f}_{7∕2})}^{\ensuremath{-}1}{({p}_{3∕2}{f}_{5∕2})}^{2}{({g}_{9∕2})}^{1}\ensuremath{\nu}{({p}_{3∕2}{f}_{5∕2})}^{4}{({g}_{9∕2})}^{2}$ configuration. There are several possible interpretations of the second band but it is difficult to distinguish between the different possibilities.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
