 Title    Positronium Quadrupole Interactions in Crystals  
 Abstract    It is shown that, due to the hyperfine interaction between the electron and the positron, positro­ nium atoms in a crystal can acquire an effective quadrupole moment and a tensor polarizability. In such a case the effective quadrupolar interaction with intracrystalline fields leads to a quadrupolar splitting of the triplet level of positronium and also to an anisotropy of its magnetic quenching in the presence of an external magnetic field. The possibilities of observating this anisotropy experimen­ tally are discussed.
