### Measurements of single top-quark production with the ATLAS detector.

W. H. Bell
These proceedings summarise the single top-quark production cross-section results obtained with the ATLAS~\cite{:2008zzm} detector at a centre-of-mass energy of 7~\TeV. Cross-section results for the $t$, $Wt$ and $s$-channels are presented. These results are interpreted in terms of the CKM matrix element $|\Vtb|$ assuming $|\Vtb| \gg |\Vts|$ and $|\Vtd|$. Searches for flavour changing neutral-currents and right-handed \Wprime\ in single top-quark events are also presented.
