Abstract

fetched live from OpenAlex

The reduced transition probabilities, $B(E2;{0}_{\mathrm{gs}}^{+}\ensuremath{\rightarrow}{2}_{1}^{+})$, have been measured in the radioactive isotopes $^{108,106}\mathrm{Sn}$ using subbarrier Coulomb excitation at the REX-ISOLDE facility at CERN. Deexcitation $\ensuremath{\gamma}$ rays were detected by the highly segmented MINIBALL Ge-detector array. The results, $B(E2;{0}_{\mathrm{gs}}^{+}\ensuremath{\rightarrow}{2}_{1}^{+})=0.222(19){e}^{2}{b}^{2}$ for $^{108}\mathrm{Sn}$ and $B(E2;{0}_{\mathrm{gs}}^{+}\ensuremath{\rightarrow}{2}_{1}^{+})=0.195(39){e}^{2}{b}^{2}$ for $^{106}\mathrm{Sn}$ were determined relative to a stable $^{58}\mathrm{Ni}$ target. The resulting $B(E2)$ values are $\ensuremath{\sim}30%$ larger than shell-model predictions and deviate from the generalized seniority model. This experimental result may point towards a weakening of the $N=Z=50$ shell closure.

Full frame distilled prediction

Teacher imitation

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.
