Deformed shell model results for two-neutrino double-beta decay of <sup>82</sup>Se
Bibliographic record
Abstract
The half-life for two-neutrino double-beta decay has been calculated for 82 Se, within the framework of the deformed shell model (DSM) based on Hartree–Fock states employing a modified Kuo interaction in 2 p 3/2 , 1 f 5/2 , 2 p 1/2 , and 1 g 9/2 space with single particle energies (relative to a 56 Ni core) for the four orbitals taken as 0.0, 0.78, 1.08, and 4.25 MeV, respectively. A reasonable description is obtained for the spectroscopic properties of yrast levels in 82 Se, and similarly in the past 82 Kr was studied successfully using DSM. The half-life calculated using DSM is ∼3.56 × 10 20 a compared to the experimental value (0.92 ± 0.07) × 10 20 a. We have also recalculated the half-life by including the 1 f 7/2 orbit in the preceding model space using the fpg interaction introduced by Sorlin et al. (Phys. Rev. Lett. 88, 092501 (2002)). The calculated half-life is 2.05 × 10 19 a (0.58 × 10 20 a if we include the quenching factor of 0.77).

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.
