Stopping residuals against measurements
Each electronic-stopping model of the stopping chapter compared with every measured stopping dataset committed under validation/data/stopping/ (format: lindhard-stopping-data/1, docs/stopping-data-format.md). Only data admitted by docs/data-provenance.md are in that directory; no NIST, IAEA or SRIM-derived value is read or shown.
Regenerate this page with
cargo run -p lindhard-plots --bin lindhard-stopping-report
and check it is current with the same command and -- --check. The output is a pure function of the committed datasets and the models, so running it twice gives the same bytes.
How to read the tables
- A residual is
model - measured; positive means the model is above the measurement. Relative residuals aremodel / measured - 1. - Stopping is a cross section per target atom (per average atom for a compound), in eV·10⁻¹⁵ cm². Mean and rms are the mean and root mean square of the absolute residual in that unit; rel. mean and rel. rms are those of the relative residual.
- A point the model cannot evaluate is skipped: it is counted in the skipped column, listed with the model’s reason, and is in no statistic.
- Where a system is one ion on one element, a per-pair correction of each model (a Chebyshev polynomial of degree 2 in ln E for the log of the measured-to-model ratio,
lindhard::ion::stopping::correction) is fitted to the training points. 3 interior points chosen with seed 20261015 are held out of the fit. The corrected and uncorrected statistics on the held-out points are shown side by side; whether the correction helps is stated either way. The correction applies only inside the energy span of the training points.

Stopping cross section of Cu for protons, 50 to 600 keV, as printed in Table I of Bader et al. (1956); values from the authors’ smooth curves through their measured points
Source: M. Bader, R. E. Pixley, F. S. Mozer and W. Whaling, Phys. Rev. 103, 32 (1956)
Note: the paper states no uncertainty for these values, so sigma is 0 (none stated)
