## Abstract

We have calculated differential, total and transport cross sections for muonic hydrogen in the n=2 state scattering from hydrogen. The metastable fraction of the 2S state that slows down below the 2P threshold without undergoing collisional quenching has been calculated as a function of the initial kinetic energy using a Monte Carlo kinetics program. Contrary to earlier estimates, the metastable fraction in the kinetic energy range of 2-5 eV cannot be neglected.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
