Double -β Decay Q values of Te130, Te128, and Te120
Bibliographic record
Abstract
The double-β-decay Q values of Te130, Te128, and Te120 have been determined from parent-daughter mass differences measured with the Canadian Penning Trap mass spectrometer. The Xe132-Xe129 mass difference, which is precisely known, was also determined to confirm the accuracy of these results. The Te130 Q value was found to be 2527.01A±0.32 keV, which is 3.3 keV lower than the 2003 Atomic Mass Evaluation recommended value and is consistent with another recent Penning trap measurement. The Te128 and Te120 Q values were found to be 865.87A±1.31 and 1714.81A±1.25 keV, respectively. For Te120, this reduction in uncertainty of nearly a factor of 8 opens up the possibility of using this isotope for sensitive searches for neutrinoless double-electron capture and electron capture with β+ emission. © 2009 The American Physical Society.

How this classification was reachedexpand
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.
