Mass measurements of proton-rich nuclides in the vicinity of <sup>92</sup>Ru and <sup>93</sup>Rh for νp-process models
Bibliographic record
Abstract
One of the long-standing questions in our understanding of the origin of the elements is the significant underproduction of light-p nuclei such as 92Mo and 94Mo by models of nucleosynthesis in various astrophysical scenarios. The recently proposed νp-process [1], which occurs due to the interaction of the neutrino wind with the proton-rich ejecta of core collapse supernova explosions, is a process which could resolve the underproduction of 92Mo and 94Mo. The final abundances of these two isotopes as well as any others synthesized by the νp-process depend directly on the values of the proton separation energies, Sp, along the νp-process reaction path; the Sp value of 93Rh is thought to be especially critical to the relative production of 92Mo and 94Mo [2]. Due to the absence of mass measurements in this region Sp(93Rh) and many of the other required Sp values were not well known. Recent mass measurements performed with the Canadian Penning Trap mass spectrometer have reduced uncertainties in the Sp values of many of the proton-rich nuclei between Mo and Pd including S p(93Rh) by factors of as much as 60. These measurements and the resulting implications for both the ∪-process path and the 92Mo/94Mo abundance ratio will be discussed. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlikeLicence.

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.
