The possible existence of light sterile neutrinos is of great interest in many areas of particle physics, astrophysics, and cosmology. Furthermore, should the MiniBooNE experiment at Fermilab confirm the Liquid Scintillating Neutrino Detector (LSND) oscillation signal, then new measurements are required to identify the mechanism responsible for these oscillations. Possibilities include sterile neutrinos, CP or CPT violation, variable mass neutrinos, Lorentz violation, and extra dimensions. In this paper, we consider an experiment at a stopped pion neutrino source to determine if active-sterile neutrino oscillations with \ensuremathΔm2 greater than 0.1 eV2 can account for the signal. By exploiting stopped \ensuremathπ+ decay to produce a monoenergetic \ensuremathν_\ensuremathμ source, and measuring the rate of the neutral current reaction \ensuremathνx12C\ensuremath→\ensuremathνx12C*(15.11) as a function of distance from the source, we show that a convincing test for active-sterile neutrino oscillations can be performed.
