In-trap decay spectroscopy on highly charged radioactive ions towards measurements on intermediate nuclei in beta beta decay
Bibliographic record
Abstract
Diese Arbeit beschreibt die Entwicklung und Inbetriebnahme einer neuen Zerfallsspektroskopieanlage mit dem Ziel die schwachen Elektroneneinfangs-Verzweigungsverhältnisse der uu-Zwischenkerne im doppelten Betazerfall zu bestimmen. Die experimentell gewonnenen Daten sind von Bedeutung für theoretische Schalenmodellrechnungen, zur Bestimmung der Kernmatrixelemente des doppelten Betazerfalls. Hauptbestandteil der neuartigen Anlage ist eine Elektronenstrahl-Ionenfalle des TITAN (TRIUMF's Ion Trap for Atomic and Nuclear science) Experiments am TRIUMF in Vancouver, Kanada, mit welcher radioaktive Ionen durch eine Kombination aus elektrischen und magnetischen Felder und ohne Implantierung auf einem Trägermaterial gespeichert werden können. Neben der effektiven Reduzierung des Untergrunds, bietet die Verwendung der EBIT den Vorteil einer nahezu verlustfreien Speicherung von hochgeladenen Ionen, wodurch eine präzise Messung von Halbwertszeiten ermöglicht wird.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
