Abstract
We study the possibilities offered by muon storage rings
for
appearance
experiments in order to determine masses and mixing angles for the
and
oscillations. The dependence of
tau event rates on baseline, forward peaking of decay
neutrinos with increasing energies,
and average fluxes intercepted by detectors of
various sizes is discussed. It is found that the baseline length does not
significantly affect the rates for oscillations of
such magnitudes as are
suggested by the current atmospheric neutrino data.
Subsequently, the effects of cuts on hadronic and
wrong sign leptonic modes are computed and used to plot 
CL contours
for the parameter regions that can be explored in such experiments.
The results show that even for modest muon beam energies,
convincing coverage and verification of the
Super Kamiokande parameters is possible. In addition, a very significant
enlargement of present day bounds on the mixing parameters for neutrino
oscillations of all types is guaranteed by these types of searches.
