Abstract
We have identified the muonium signal that is enhanced by an electric field in semi-insulating GaAs at $10\phantom{\rule{0.3em}{0ex}}\mathrm{K}$. Experiments were conducted with the electric field applied parallel and antiparallel to the incoming muon. For fields in the range $\ensuremath{\approx}1--15\phantom{\rule{0.3em}{0ex}}\mathrm{kV}∕\mathrm{cm}$ in both directions the nuclear dipolar broadening of the muon spin precession signal at $1\phantom{\rule{0.3em}{0ex}}\mathrm{T}$ is consistent with that of positively charged muonium (i.e., ${\mathrm{Mu}}^{+}$). This is confirmed by muon-nuclear level crossing measurements at $\ifmmode\pm\else\textpm\fi{}20\phantom{\rule{0.3em}{0ex}}\mathrm{kV}∕\mathrm{cm}$ which show a resonance signal identical to that of isolated ${\mathrm{Mu}}^{+}$ seen previously in $p$-type GaAs. These measurements show by direct spectroscopic means that the electric field of either direction enhances the probability to form isolated ${\mathrm{Mu}}^{+}$ in high resistivity GaAs and are in agreement with a model in which the electric field prevents the formation of neutral bond centered muonium.

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 it
