Measurement of k0 values for europium, lutetium and iridium at FRM II with a very well thermalized neutron spectrum
Bibliographic record
Abstract
Abstract The k 0 values of 6 non-1/ v nuclides ( 152 Eu, 152m Eu, 154 Eu, 177 Lu, 192 Ir and 194 Ir) were determined using the extended Høgdahl formalism at the research reactor FRM II with very high f values. Standards were irradiated in 4 channels at different local temperatures between 40 °C and 55 °C measured using temperature sensitive irreversible labels. A good agreement with the recommended values was found for 152 Eu, 154 Eu and 177 Lu using the original g ( T n ) factors by Gryntakis, however, the k 0 values for 152m Eu in this work were 7% higher. New k 0 values were also determined using the g ( T n ) factors by Van Sluijs. Differences up to 6% were found for Eu isotopes compared with the recommended values. The recommended k 0 values for 192 Ir and 194 Ir could be confirmed using g = 1. The theoretical k 0 values for 177 Lu were calculated using new nuclear data. They are up to 6% less than the recommended values. The present k 0 values determined in this work showed a similar trend. The influence of different g ( T n ) factors on the determination of the k 0 values was investigated.

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.
