Abstract
Recently, the bound and continuum spectrum of $^{11}\mathrm{Be}$ has been calculated within the ab initio no-core shell model with continuum (NCSMC) method, with the parity inversion in the ground state successfully reproduced. The continuum spectrum obtained is in agreement with known experimental levels. The S matrix contained in the NCSMC continuum wave functions of the $\mathrm{n}+^{10}\mathrm{Be}$ system is used in this work for the first time in a transfer-to-the-continuum (TC) reaction calculation. The TC approach is applied to study the excitation energy spectrum of $^{11}\mathrm{Be}$ measured in the $^{9}\mathrm{Be}(^{18}\mathrm{O},^{16}\mathrm{O})^{11}\mathrm{Be}$ reaction at 84 MeV. Previously known levels are confirmed and theoretical and experimental evidence for a 9/${2}^{+}$ state at ${E}_{x}=5.8$ MeV is given, whose configuration is thought to be $^{10}\mathrm{Be}({2}^{+})+\mathrm{n}({d}_{5/2})$.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
