Measuring the $\nu_{\mu}$ to $\bar{\nu_{\mu}}$ Ratio in a High   Statistics Atmospheric Neutrino Experiment
  By exploiting differences in muon lifetimes it is possible to distinguish $\nu_{\mu}$ from $\bar{\nu_{\mu}}$ charged current interactions in underground neutrino detectors. Such observations would be a useful tool in understanding the source of the atmospheric neutrino anomaly.
