Electron impact ionization cross sections of atoms
Bibliographic record
Abstract
In this article, we report the electron impact ionization cross sections for atoms Si, P, S, Sc, Cr, Mn, Co, Zn, Ga, Ge, Nb, Rh, and Cd, having applications in different areas of applied science and technology. The energy regime for the calculation is from the ionization threshold of the target to 2000 eV. We have employed the spherical complex optical potential method to calculate inelastic cross sections. A semiempirical complex scattering potential ionization contribution method is then used to estimate the ionization cross section from the inelastic cross section. In general, good agreement between the present results with available theoretical datasets and measurements are observed. The prime focus of this study was to investigate electron impact ionization phenomena in less studied targets. The results obtained are found to be quite encouraging. The values presented here are reasonable estimates of cross section for all the atoms studied.

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.
