Abstract

fetched live from OpenAlex

The heavy-ion radiative capture reaction ${}^{12}$C(${}^{16}$O,$\ensuremath{\gamma}$)${}^{28}$Si has been studied at three energies ${E}_{\mathrm{c}.\mathrm{m}.}=8.5$, 8.8, and 9 MeV which are close to the Coulomb barrier. The weak radiative capture process has been identified by measuring the ${}^{28}$Si recoils in the highly selective 0${}^{\ensuremath{\circ}}$ spectrometer DRAGON at TRIUMF (Vancouver). The coincident $\ensuremath{\gamma}$ rays have been recorded in the associated BGO array. This has allowed a complete measurement of the $\ensuremath{\gamma}$ spectrum and the relative strength of all decay pathways. An important part of the decay through quasibound states close to the particle threshold and the feeding of bound states with particular deformation have been identified for the first time. Comparisons with Monte Carlo simulations allowed the extraction of the full experimental radiative capture cross section. Our results suggest an important contribution of spins ${J}^{\ensuremath{\pi}}={5}^{\ensuremath{-}}$ and 6${}^{+}$ in the entrance channel. The surprisingly large cross sections from 12 $\ensuremath{\mu}$b at ${E}_{\mathrm{c}.\mathrm{m}.}=8.5$ MeV to 25 $\ensuremath{\mu}$b at ${E}_{\mathrm{c}.\mathrm{m}.}=9.0$ MeV for the heavy-ion radiative capture process are discussed in terms of the interplay between statistical and structural aspects of the process.

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.
