Abstract
Compound resonances in nucleus-nucleus scattering (bound states in the continuum) relate to bound states in the subsystems. Both types of resonances can be studied in a unified and general framework by a model for the scattering that uses Sturmian expansions of multichannel interactions between the colliding nuclei. Associated with such expanded multichannel interactions are algebraic multichannel scattering matrices. As an example, we have used the collective model (to second order) to define the interaction potentials for low energy neutron- 12C scattering allowing coupling between the ground 0+1, 2+1 (4.44 MeV), and 0+2 (7.64 MeV) states. The algebraic S matrix for this system then has been evaluated and cross sections as a function of energy obtained Resonance structures occur naturally and are reflected in the actual measured data.

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 it
