Breathing-mode measurements in Sn isotopes and isospin dependence of nuclear incompressibility
Bibliographic record
Abstract
T. Li et al. [Phys. Rev. C 81, 034309 (2010)] have analyzed the measured breathing-mode energies of some tin isotopes in terms of a first-order leptodermous expansion and found the value of $\ensuremath{-}550\ifmmode\pm\else\textpm\fi{}100$ MeV for the symmetry-incompressibility coefficient ${K}_{\ensuremath{\tau}}$. Removing an approximation that they made, we find that the first-order estimate of ${K}_{\ensuremath{\tau}}$ shifts to $\ensuremath{-}661\ifmmode\pm\else\textpm\fi{}144$ MeV. However, taking into account higher-order terms in the leptodermous expansion shows that the data are compatible with the significantly lower magnitudes indicated by both another experiment and some theoretical estimates. In particular, there does not appear to be any conflict between the breathing-mode data and a value of ${K}_{\ensuremath{\tau}}$ consistent with most Skyrme forces.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
