Abstract

fetched live from OpenAlex

In the present work, the multiple scattered fraction (MSF) was investigated experimentally for HgO and PbO targets of various thicknesses. The targets were excited by 59.54 keV gamma rays emitted from a 5 Ci 241 Am annular radioactive source and the emitted photons were collected using a high-resolution HPGe semiconductor detector with a resolution of 182 eV at 5.9 keV placed at a scattering angle of 168°. Our results show that the number of multiple scattered photons exponentially increases with the increase of target thickness for scattering (Compton and coherent) and characteristic (Kα 2 and Kα 1 ) peaks and then saturates at a particular value of the target thickness called saturation thickness.

Full frame distilled prediction

Teacher imitation

Not 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.
