In this work, we present a joint experimental and theoretical effort to gain insights into the atomistic details of hydrogen atom scattering at the $\\alpha$-Al$_2$O$_3$(0001) surface. Surprisingly, this system has been hardly studied to date, although hydrogen atoms as well as $\\alpha$-Al$_2$O$_3$ are omnipresent in catalysis as reactive species and support oxide, respectively.
