Abstract

fetched live from OpenAlex

The $^{15}\mathrm{O}$($\ensuremath{\alpha},\ensuremath{\gamma}$)$^{19}\mathrm{Ne}$ reaction plays a role in the ignition of type I x-ray bursts on accreting neutron stars. The lifetimes of states in $^{19}\mathrm{Ne}$ above the $^{15}\mathrm{O}$$+\ensuremath{\alpha}$ threshold of 3.53 MeV are important inputs to calculations of the astrophysical reaction rate. These levels in $^{19}\mathrm{Ne}$ were populated in the $^{3}\mathrm{He}$($^{20}\mathrm{Ne}$,$\ensuremath{\alpha}$)$^{19}\mathrm{Ne}$ reaction at a $^{20}\mathrm{Ne}$ beam energy of 34 MeV. The lifetimes of six states above the threshold were measured with the Doppler-shift attenuation method. The present measurements agree with previous determinations of the lifetimes of these states and in some cases are considerably more precise.

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.
