We study theoretically and experimentally a nominally stadium shaped quantum billiard, a device in which the classical dynamics is expected to be chaotic. Using self-consistent solutions for the confining potential in our calculations, we find, in agreement with experiment, that the magnetotransport is dominated by a periodic oscillations, characteristic of regular orbits in the structure, indicating the stability of non-chaotic classical trajectories.
