Depolarization of high-energy neutral particles in crystals and the   possibility to measure anomalous magnetic moments of short-lived hyperons
  The degree of depolarization of neutral particles in crystals can reach tens of percents over the crystal length of several centimeters, which can be the basis for possible experimental application of the depolarization effect for measuring anomalous magnetic moments of short-lived neutral hyperons.
